Abstract
Heat Pipe is a heat transfer device used in many applications and it is very similar in some respects to the thermosyphon. Since there were several limitations of thermosyphon, heat pipe was developed. The idea of the heat pipe was first suggested in 1942, since then over a several decades the serious development of a heat pipe took place. Heat pipe mainly consists of three regions viz. evaporator, adiabatic and condenser section. The heat pipe differs from the thermosyphon by virtue of its ability to transport heat against gravity by an evaporation-condensation cycle. This research work includes experimentation on available heat pipe, development of CFD model and its validation with experimental results using CFD Tool. The results obtained by CFD are in good agreement with an experimental results. Since the heat pipe is used for transferring the heat, this research work focuses on increasing the heat transfer by modified model, modifications in terms of increased surface area, is proposed. From CFD analysis it was found that the proposed modified heat pipe shows enhancement in performance in terms of heat transfer rate by 19% when it is simulated for without heat sink case and 45% while with heat sink case, compared to conventional heat pipe. The mixture multiphase model from CFD too is used for simulation of heat pipe.

cooling oil cavity area and cooling oil cavity location, the diesel engine piston cooling effect and structure
parameters’ influences on the piston temperature field were studied. The results showed that: appropriately
increasing the cross-section of the cooling gallery is favorable for heat dissipation, but over-dimension will lead to
small cooling liquid filling ratio and thus impede the cooling; The movements of cooling gallery of the piston will
have great effect on the top of the piston, the combustion chamber, the fire shore, the first ring shore and the top of
the inner chamber. The research of this paper provides a basis for engine piston cooling design.

The Engine cylinder is one of the major automobile components, which is subjected to high temperature variations and thermal stresses. In order to cool the cylinder, fins are provided on the cylinder to increase the rate of heat transfer. By doing thermal analysis on the engine cylinder fins, it is helpful to know the heat dissipation inside the cylinder. The principle implemented in this project is to increase the heat dissipation rate by using the invisible working fluid, nothing but air. As know, by increasing the surface area we can increase the heat dissipation rate, so designing such a large complex engine is very difficult. The main purpose of using these cooling fins is to cool the engine cylinder by air. The main aim of the project is to analyse the thermal properties by varying geometry, material, distance between the fins and thickness of cylinder fins. Parametric models of cylinder with fins have been developed to predict the transient thermal behaviour. The models are created by varying the geometry circular and also by varying thickness of the fins for both geometries. The 3D modelling software used is Pro/Engineer. Thermal analysis is done on the cylinder fins to determine variation temperature distribution over time. The analysis is done using ANSYS. Thermal analysis determines temperatures and other thermal quantities. In this thesis, using materials cast iron, Copper and Aluminium alloy 6082 are also for cylinder fin body. Thermal analysis is done using all the three materials by changing geometries, distance between the fins and thickness of the fins for the actual model of the cylinder fin body. K. Karthikeyan | C.

Effect of Different Fin Geometries on Heat Transfer Coefficientijtsrd
High rate of heat flow is the demand of number of engineering applications, heat exchangers used in process industries, economizers used to heat water to boiler or activities like cooling of IC engines. Also, the removal of heat from integral circuit or exchange of heat between two fluids as in nuclear power plants many researchers contributed in enhancement of heat transfer through various approaches. Increase in heat transfer rate and to derive is being done by using different techniques or by performing experiments as well previous literature mentioned the theory regarding heat transfer in such a way that it will increased by increasing area and heat transfer coefficient. In case of natural convection there is only scope for increasing heat transfer area, there extended surfaces i.e. fins are better option to it. Other advantage is increasing turbulence with pitch therefore it enhances heat transfer. Study of heat transfer is possible through numerical experimental analysis. In case of numerical analysis, the results give's heat flow pattern and but less accurate. Whereas experimental analysis gives accurate results but require set up, time and valid conditions.

Numerical analysis of heat sinks for led lighting moduleseSAT Journals
Abstract
LEDs provide efficient lighting solutions. Their main advantages are efficiency, reliability and durability. Although LEDs operate cooler than conventional incandescent bulbs, it is necessary to achieve maximum heat transfer in order to maintain or improve their efficiency and lifespan. Heat sinks in LED modules provide a path for heat to flow from the source to the outside ambience. Heat sinks with different fin geometries are analyzed to determine its influence on thermal performance and airflow around the fins. By comparing different fin geometries, the thermal performance and airflow are compared and analyzed. It was found that the airfoil fins with reverse orientation offers the minimum resistance. Airfoil is the most commonly used shape in applications where aerodynamics is of major importance.

Computational analysis of heat transfer through four-stroke S. I. engine finsijsrd.com
it is important for an air-cooled engine to utilize fins for effective engine cooling to maintain uniform temperature in the cylinder periphery. Many experimental works has been done to improve the heat release of the cylinder and fin efficiency. In this study, heat release of an IC engine cylinder cooling with straight fins and with wavy fins is calculated numerically using commercially available CFD tool ANSYS. The IC engine is initially at 500⁰C and the heat release from the cylinder is analysed at a wind velocity of 60 km/hr to 100 km/hr. The heat release from both the cylinders is compared. With the help of the available numerically results, the design of the I. C. engine cooling fins can be modified for improving the heat release and efficiency.

Thermo Structural Analysis on Cylinder Head of 4 Stroke VCR Diesel EngineDr. Amarjeet Singh
The main aim of the project is to analyse the design performance of VCR 4 stroke Diesel engine cylinder head at the compression ratio 16.5 using Ansys software. The basic modelling is done on CATIA V5 software. The design exposition can be done structurally and thermally in ansys. By the structural analysis the maximum and minimum von misses stress, total deformation can be determined, the maximum gas pressure required for this analysis is taken from the experimental set up of VCR engine. With the steady state thermal analysis we will get the maximum temperature distribution and total heat flux of the cylinder head with the initial pressure value. The results of both the expositions are used to decide the critical areas of the cylinder head which require further amendment and also the quality of design. If the maximum stress is less than the material strength of the cylinder head then the basic design criteria can be achieved.

The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
