Diesel is a fossil fuel that is getting depleted at a fast rate. So an alternative fuel is
necessary and a need of the hour. simarouba oil, which is cultivated in India at large scales, has a
high potential to become an alternative fuel to replace diesel fuel. Direct use of simarouba oil cannot
be done, as its viscosity is more than the diesel fuel, and hence affects the combustion characteristics.
The simarouba oil is esterified to reduce the viscosity and it is blended with diesel on volume basis in
different proportions. The use of thermal barrier coatings (TBCs) to increase the combustion
temperature in diesel engines has been pursued for over 20 years. Increased combustion temperature
can increase the efficiency of the engine, decrease. However, TBCs have not yet met with wide success
in diesel engine applications because of various problems associated with the thermo-mechanical
properties of the coating materials. Although, the in-cylinder temperatures that can be achieved by the
application of ceramic coatings can be as high as 850-9000C compared to current temperatures of
650-7000C. The increase in the in-cylinder temperatures helped in better release of energy in the case
of biodiesel fuels thereby reducing emissions at, almost the same performance as the diesel fuel. Here
the effort has been made to determine the performance and emission characteristics of SOME blend
with diesel in conventional engine and LHR engine

The use of methyl esters of vegetable oil known as biodiesel are increasingly popular because of their low impact on environment, green alternate fuel and most interestingly it’s use in engines does not require major modification in the engine hardware. Use of biodiesel as sole fuel in conventional direct injection diesel engine results in combustion problems, hence it is proposed to use the biodiesel in low heat rejection (LHR) diesel engines with its significance characteristics of higher operating temperature, maximum heat release, higher brake thermal efficiency (BTE) and ability to handle the lower calorific value (CV) fuel. In this work biodiesel from Neem kernel oil was used as sole fuel in LHR direct injection (DI) diesel engine. The low heat rejection engine was developed with uniform metal matrix composites (MMC) coating of cylinder head. The experimental investigation was carried out in a single cylinder water-cooled LHR direct injection diesel engine. In this investigation, the combustion, performance and emission analysis were carried out in a diesel and biodiesel fueled LHR engine under identical operating conditions. The brake thermal efficiency (BTE) of LHR engine with biodiesel is decreased marginally than LHR engine operated with diesel. Carbon monoxide (CO) and Hydrocarbon (HC) emission levels are decreased but in contrast the Oxide of Nitrogen (NOx) emission level was increased due to the higher peak temperature. In the final analysis, it was found that, the results are quite satisfactory.

The micro air bubbles in concrete mix act as fine aggregates which lead to reduction of the
aggregates. The reduction of fine aggregates will cause reduction of water required for concrete mix
without impairing the strength of concrete mix. This reduction has to be considered in designing an air
entrained concrete mix. Theoretical (equations) and experimental study have been carried out to study the
effect of air entrainment on compressive strength, density and ingredients of fresh concrete mix. During
all the study, water cement ratio (w/c) was maintained constant at 0.5 to study the affection of air
entrainment (a %) on concrete mix. The results have shown substantial decreasing in cement, water,
aggregates and concrete density followed with decreasing in compressive strength of concrete. The results
of this study has given more promising to use it as a guide for concrete mix design to choose the most
appropriate concrete mix design economically.

Evaluation of Compressive Strength and Water Absorption of Styrene Butadiene...IJMER
In this research, effect of Styrene-Butadiene Rubber (SBR) latex on water absorption and
compressive strength of concrete has been studied. A locally available “RIPSTAR-148” is used as SBR
Latex.
It has been observed that SBR latex improves the internal structure of the latex modified
concrete resulting in considerable reduction in the water absorption value at 28 days of age. However,
at early age, the effect of SBR latex on water absorption is adverse. Same trend is noticed for the
compressive strength; at 7 days of age, SBR latex has negative effect while at 28 days, the addition of
SBR latex in concrete results in enhancement of compressive strength. Based on the results of this
study, latex modified concrete made using “RIPSTAR-148” may be recommended to be used in RC
structures in INDIA. However, for the mixes rich in cement, the dosage of “RIPSTAR-148” needs to be
adjusted to maintain required workability of concrete.

Shot peening procedures developed over the ago in substantial improvements of fatigue properties and Fatigue life. The use of shot peening on aluminium 7075-T6 plates to improve fatigue properties and improve resistance to stress on the corrosion cracking with help of glass beads and various peening methods. When these components subsequently are loaded in tension or bending to a
stress level in the range below the required for yield, the actual tensile stress at the surface is lower than
that calculated on the basis of load and cross sectional area. Fatigue are major problem which normally
start at or near the surface stressed in tension, thus processes that produce residual surface compressive
stresses in components usually enhance the resistance to fatigue. The impact of glass shots which create
resistance after the shot penning process carried out and also control the effects of failure on aluminium

Experimental Investigation on Use of Honge(Pongamia) Biodiesel on Multi-cylin...ijsrd.com
Biodiesel is a fatty acid alkyl ester which is renewable, biodegradable and non toxic fuel which can be derived from any vegetable oil by transesterifiaction process. Biodiesel has become a key source as a substitution fuel and is making its place as a key future renewable energy source. Biodiesel derived from vegetable oils are quite promising alternative fuels for diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity. The performance of vegetable oils can be improved by modifying them through the Transesterification process. In the present work, the performance of single cylinder direct injection diesel engine using honge as fuel was evaluated for its performance, emission and combustion characteristics. The properties of honge thus obtained are comparable with ASTM biodiesel standards. The produced honge biodiesel was tested for their use as a substitute fuel for diesel engine. Tests have been conducted at different varying load of biodiesel, at 60% throttle. The performance parameters elucidated includes brake thermal efficiency, specific fuel consumption, torque, also emission characteristics against varying Brake Power (BP) and combustion characteristics against crank angle.

Geochemistry and Genesis of Kammatturu Iron Ores of Devagiri Formation, Sandu...IJMER
The Greenstone belts of Karnataka are enriched in BIFs in Dharwar craton, where Iron
formations are confined to the basin shelf, clearly separated from the deeper-water iron formation that
accumulated at the basin margin and flanking the marine basin. Geochemical data procured in terms of
major, trace and REE are plotted in various diagrams to interpret the genesis of BIFs. Al2O3, Fe2O3 (T),
TiO2, CaO, and SiO2 abundances and ratios show a wide variation. Ni, Co, Zr, Sc, V, Rb, Sr, U, Th,
ΣREE, La, Ce and Eu anomalies and their binary relationships indicate that wherever the terrigenous
component has increased, the concentration of elements of felsic such as Zr and Hf has gone up. Elevated
concentrations of Ni, Co and Sc are contributed by chlorite and other components characteristic of basic
volcanic debris. The data suggest that these formations were generated by chemical and clastic
sedimentary processes on a shallow shelf. During transgression, chemical precipitation took place at the
sediment-water interface, whereas at the time of regression. Iron ore formed with sedimentary structures
and textures in Kammatturu area, in a setting where the water column was oxygenated.

Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

development process that may enhance the probability of system success.
Material Parameter and Effect of Thermal Load on Functionally Graded CylindersIJMER
The present study investigates the creep in a thick-walled composite cylinders made
up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution
of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of
the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep
law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is
applied gradually and steady state condition of stress is assumed. The creep parameters required to
be used in creep law, are extracted by conducting regression analysis on the available experimental
results. The mathematical models have been developed to describe steady state creep in the composite
cylinder by using von-Mises criterion. Regression analysis is used to obtain the creep parameters
required in the study. The basic equilibrium equation of the cylinder and other constitutive equations
have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle
content and temperature on the stresses in the composite cylinder has been analyzed. The study
revealed that the stress distributions in the cylinder do not vary significantly for various combinations
of particle size, particle content and operating temperature except for slight variation observed for
varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development
of superior heat resistant materials.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

I. Introduction
Petroleum based fuels play a vital role in rapid depletion of conventional energy sources along with increasing demand and also major contributors of air pollutants. Major portion of today’s energy demand in India is being met with fossil fuels. Hence it is high time that alternate fuels for engines should be derived from indigenous sources. As India is an agricultural country, there is a wide scope for the production of vegetable oils (both edible and non-edible) from different oil seeds. The present work focused only on non-edible oils as fuel for engines, as the edible oils are in great demand and far too expensive. The past work revealed that uses of vegetable oils for engines in place of diesel were investigated. Though the concerned researchers recommended the use of vegetable oils in diesel engines, there was no evidence of any practical vegetable oil source engines. It is known that the efficiency of internal combustion diesel engines changes 38-42%. It is about 60% of the fuel energy dismissed from combustion chamber. To save energy, combustion chamber component are coated with low thermal conduction materials. The effect of thermal barrier coating on the cylinder components like piston crown top, cylinder liner, cylinder head inside and valves. The thermal barrier coated engines are otherwise known as low heat rejection (LHR) engines. Due to the insulation of the cylinder wall the heat transfer through the cylinder walls to the cooling system is reduced which change the combustion characteristics of the diesel engine. To know the changes during combustion the steady-state LHR engines operation have been studied by applying either the first or second law of thermodynamics. The state of the art of the thermal barrier coating is the yattria stabilized zirconia. In addition, other material systems have been investigated for the next generation of TBC. The study also focuses on coating method for Yattria Stabilized Zirconia (YSZ) to improve coating under high load and temperature cyclical conditions encountered in the real engine. The effect of insulation on engine performance, heat transfer characteristics, combustion and emission characteristics are studied and compared with standard (STD) diesel engine
II. Materials and Methods
The extraction of biodiesel is carried out by base catalyzed transesterification method.
Abstract: Diesel is a fossil fuel that is getting depleted at a fast rate. So an alternative fuel is necessary and a need of the hour. simarouba oil, which is cultivated in India at large scales, has a high potential to become an alternative fuel to replace diesel fuel. Direct use of simarouba oil cannot be done, as its viscosity is more than the diesel fuel, and hence affects the combustion characteristics. The simarouba oil is esterified to reduce the viscosity and it is blended with diesel on volume basis in different proportions. The use of thermal barrier coatings (TBCs) to increase the combustion temperature in diesel engines has been pursued for over 20 years. Increased combustion temperature can increase the efficiency of the engine, decrease. However, TBCs have not yet met with wide success in diesel engine applications because of various problems associated with the thermo-mechanical properties of the coating materials. Although, the in-cylinder temperatures that can be achieved by the application of ceramic coatings can be as high as 850-9000C compared to current temperatures of 650-7000C. The increase in the in-cylinder temperatures helped in better release of energy in the case of biodiesel fuels thereby reducing emissions at, almost the same performance as the diesel fuel. Here the effort has been made to determine the performance and emission characteristics of SOME blend with diesel in conventional engine and LHR engine.

2.1. Process of Extracting
Fig 2.1: The flow chart for biodiesel production
To a one liter of raw Simaroauba oil is heated up to 700C. 300 ml of methanol & 5-7gms of NaOH
(catalyst) is added and the mixture is maintained at 65-700C is about 1½ hours and stirred continuously. The
mixture is allowed to settle for 20-30 min until the formation of biodiesel and glycerin layers. The glycerin is
removed from the bio-diesel in a separating funnel. The bio diesel produced from Simarouba oil is ready to use.
2.2. Transesterification
It is most commonly used and important method to reduce the viscosity of vegetable oils. In this
process triglyceride reacts with three molecules of alcohol in the presence of a catalyst producing a mixture of
fatty acids, alkyl ester and glycerol. The process of removal of all the glycerol and the fatty acids from the
vegetable oil in the presence of a catalyst is called esterification.

Chemical reaction
Physical and chemical properties are more improved in esterified vegetable oil because esterified
vegetable oil contains more cetane number than diesel fuel. These parameters induce good combustion
characteristics in vegetable oil esters. So unburnt hydrocarbon level is decreased in the exhaust. It results in
lower generation of hydrocarbon and carbon monoxide in the exhaust than diesel fuel. The vegetable oil esters
contain more oxygen and lower calorific value than diesel. So, it enhances the combustion process and generates
lower nitric oxide formation in the exhaust than diesel fuel.
III. Properties of Diesel and Some Blends
After transesterification the properties of Simarouba oil blends was determined. It was found that the
properties of Simarouba oil blends were similar to diesel. Simarouba oil blends were similar to diesel.

IV. Experimental Setup
The experimental setup enables study performance, combustion and emission characteristics. The experiments have been carried out on a DI compression ignition engine for various blends of simarouba oil with diesel (S20, S40, S60, S80, and S100) with varying brake power. The experiment is carried out at constant compression ratio of 17.5:1 and constant injection pressure of 200 bar by varying brake power.

V. Result and Discussion
After detail study of performance and emission characteristics of simarouba biodiesel and its blends in normal engine and low heat rejection engine it can be seen that 20% simarouba biodiesel blend and diesel are having same almost same characteristics so here the comparative analysis is carried out between normal engine and LHR engine.
5.1 Performance characteristics
5.1.1 Specific fuel consumption
Fig 5.1 The variation of the specific fuel consumption with brake power for diesel and simarouba blends Fig 5.1 shows the specific fuel consumption for simarouba biodiesel and its blends with respect to brake power for both normal engine and LHR engine. At maximum load the specific fuel consumption of LHR engine fuelled with biodiesel is higher than LHR engine fuelled with diesel and lower than normal engine fuelled with diesel and biodiesel. This higher fuel consumption was due to the combined effect of lower calorific value and high density of biodiesel. The test engine consumed additional biodiesel fuel in order to retain the same power output. Because the reason is heat leakage in engine cylinder is developed therefore the amount of fuel required to generate 1kw of power compare to without LHR.

5.1.2 Air fuel ratio
Fig 5.2 The variation of the air fuel ratio with brake power for diesel and simarouba blends The variation of air fuel ratio for diesel and 20% SOME blend is shown in fig 5. 2 for both normal engine and LHR engine. Fuel consumption is higher in case of LHR engine due to increased temperature and completes combustion. Air fuel ratio decreases with increase in load because air fuel mixing process is affected by the difficulty in atomization of biodiesel due to its higher viscosity. 5.1.3 Brake thermal efficiency
Fig 5.3 The variation of the brake thermal efficiency with brake power for diesel and simarouba blends The variation of the brake thermal efficiency with load for diesel and SOME blends are shown in figure 5.3. We can observe that S20 with LHR has higher brake thermal efficiency than normal engine D100 this is because of increased combustion rate which provides complete burning of fuel and due to low heat rejection. The thermal efficiency of S20 is lower than diesel because the reason is large difference in viscosity, specific gravity and volatility.

The variation of the exhaust gas temperature with load for diesel and SOME blends are shown in figure 5.4. When bio fuel concentration increases the exhaust temperature increase. The same also when load increases the exhaust temperature increases. Because the reason is the heat release rate by the biodiesel during the expansion is comparatively lower than diesel.
5.2 Emission characteristics
5.2.1 Carbon monoxide
Fig 5.5 The variation of the carbon monoxide with brake power for diesel and simarouba blends The variation of carbon monoxide (CO) with engine power output is presented in figure 5.5. The fuels are producing higher amount of carbon monoxide emission at low power outputs and giving lower values at higher power conditions. Carbon monoxide emission decreases with increasing power output. With increasing biodiesel the 20% CO emission level decreases. Biodiesel itself has about 11 % oxygen content in it and it may helps for the complete combustion. Hence, CO emission level decreases with increasing biodiesel percentage in the fuel. 5.2.2 Hydro carbon
Fig 5.6 The variation of the hydro carbon with brake power for diesel and semarouba blends The variation of hydrocarbon (HC) with respect to engine power output for different fuels are shown in figure 5.6. The high operating temperature in LHR engine makes the combustion nearly complete than the limited operating temperature condition as in the case of diesel engine. All full load hydrocarbon emission levels are decreases for LHR engine fueled with biodiesel than LHR engine fueled with diesel and diesel engine fueled with diesel. The air fuel mixture, which was accumulated in the crevice volume, was reduced due to the high temperature and availability of oxygen, which in turn leads to reduction in unburned hydrocarbon emissions.

5.2.3 Nitrogen oxide
Fig 5.7 The variation of the nitrogen oxide with brake power for diesel and semarouba blends Figure 5.7 shows the variation of oxides of nitrogen with engine power output. The main reason for the formation of oxides of nitrogen in an IC engines are high temperature and availability of oxygen. At maximum load, NOx emission for LHR engine with biodiesel fuel is higher. In LHR engine, the operating conditions are in favor of NO species and such as the availability of oxygen in the fuel itself other than the oxygen available in the air and high temperature due to insulation coating, which enhance the NO species formation.
VI. Conclusion
As detail study of performance characteristics of simarouba biodiesel and its blends on normal engine we can observe that 20% blend of simarouba biodiesel in diesel fuel has almost same mechanical efficiency, same specific fuel consumption.
We can also see that there is slight increase in brake thermal efficiency which is a positive sign with this blend.. So we can conclude that without any modification in engine we can save diesel fuel for certain extent without any compromise with standard performance characteristics and in future semarouba biodiesel can be a best alternative fuel which can replace the diesel.
As same parameters studied with engine modification, here we observed that there is increase in performance parameters than normal engine. There is increase in parameters like brake thermal efficiency, mechanical efficiency and there is decrease in specific fuel consumption and fuel consumption which can be observed in comparative graph.
By studying performance characteristics on normal engine and low heat rejection engine, it can concluded that with 20% blend we can achieve same characteristics as that of diesel fuel so S20 is the best blend and in future simarouba methyl ester can be a best and most suitable alternative fuel which can replace diesel fuel for years to come and with thermal barrier coating we can meet needy requirements.
Simarouba biodiesel shows lower heat release rate during premixed burning phase compared to diesel. The high viscosity and poor volatility of NE-D100 result in poor atomization and fuel air mixing rates. Heat release rate is more in LHR-S20 compared to LHR-D100 and heat release rate in NE-D100 and NE-S20 are almost similar.
We can conclude that the S20 with LHR shows same graphs as compared to D100 this blend is best suitable for an engine.
It was found that, CO and HC emissions for LHR engine with biodiesel was considerably lower than LHR engine fueled with diesel. This reduction of emissions due to excess oxygen availability along with higher operating temperature.
NO emission for LHR engine with biodiesel fuel was higher than LHR engine fueled with diesel. The operating conditions of LHR engine were favorable to NO formation. However this increase in emission level was within the acceptable limits.
