Basic Mechanical Engineering-Steam turbines Steve M S
Steam turbines use the pressure energy of steam to power rotation of a shaft. There are two main types: impulse turbines, where steam jet kinetic energy changes the turbine blades' momentum; and reaction turbines, where continuous steam pressure drop over fixed and moving blades provides rotational force. Compounding involves using multiple stages to reduce turbine speed for practical use, through either velocity compounding by absorbing steam kinetic energy in stages, pressure compounding by expanding steam pressure in nozzles, or a combination of both approaches in pressure-velocity compounding turbines.
This document presents information about turbines submitted by Rajeev Kumar Mandal. It includes an introduction defining turbines as devices that convert the kinetic, potential, or intermolecular energy of a fluid into mechanical energy of a rotating member. It then discusses the basic components and design of turbines. It classifies turbines based on their operation as either impulse turbines, which use fluid velocity changes to spin the turbine, or reaction turbines, which react to fluid pressure changes. Examples of different types of turbines are provided, including steam, gas, water, and wind turbines. The document focuses on steam turbines, explaining their use in power plants to generate electricity from coal, oil, or nuclear energy.
This document discusses the key aspects of a 134 MW steam turbine. It begins by defining a steam turbine as a device that extracts thermal energy from pressurized steam and converts it into mechanical energy. It then provides specific design data for a 134 MW turbine, including its rated output, speed, steam conditions, number of extractions and stages. The document goes on to classify turbines based on their steam flow, type of energy conversion, compounding, cylinder arrangement, and exhaust conditions. It describes impulse, reaction, and combined impulse-reaction turbines as well as tandem and cross-compound cylinder arrangements.
Steam blowing stages before turbine rollingabhinav kumar
Steam blowing is carried out to remove welding slag, debris, and other foreign materials from turbine system piping generated during manufacturing and construction. It uses high velocity steam to purge lines through either puffing method, which uses thermal shocks, or continuous blowing method. The process is done in stages, with target plates used to evaluate cleanliness. The lines blown include steam, reheat, bypass, and other auxiliary lines. Blowing is completed when target plates show acceptable levels of debris indentation.
Pre commissioning steam turbines load trialNagesh H
The document discusses pre-commissioning and commissioning activities for a steam turbine. Pre-commissioning includes steam blowing of lines, condenser testing like leak and vacuum drop tests, checking bearing clearances and dumps, setting throttle valves, and verifying safety trips. Commissioning procedures cover starting the turbine in solo run and load run modes while monitoring vibration levels and other parameters. Load trial data is collected and actual steam consumption is compared to projected values, with correction factors applied. Problems faced on site included low dump values due to nozzle chest welding issues and high CEP current due to pump-motor misalignment.
Turbines extract energy from moving fluids and convert it to rotational energy. The main types are water, steam, gas, and wind turbines. Water turbines include impulse turbines like Pelton and cross-flow, which use jet velocity, and reaction turbines like Francis and Kaplan, which use changing fluid pressure. Steam turbines convert thermal energy from pressurized steam. Gas turbines power aircraft and generators using combustion. Wind turbines have rotors to capture kinetic wind energy and generators to produce electricity. Turbines are used widely in power generation and industrial applications.

The document discusses improving the performance of electricity market clearing software used by the Midcontinent Independent System Operator (MISO). MISO has focused on reducing the solve time of its market clearing software to enable timely commitment of resources while maintaining high optimality. A new high performance computing based optimization engine called HIPPO is being developed under a DOE project to achieve a 10x speed improvement. HIPPO includes fast concurrent mixed integer programming and security analysis solvers. Initial tests show HIPPO providing a median 2.63x speedup over MISO's current software.
Wholesale electricity markets in the U.S. have brought significant benefits to society by maximizing social welfare while ensuring system security. Optimization models and algorithms are at the core of the software tools used to make this happen. In recent years, the Midcontinent Independent System Operator (MISO) has focused its attention on improving its market clearing software performance to enable further developments in its market products. This has largely entailed reducing solve time to ensure the timely commitment of resources and maintaining high optimality in the solutions. With rapid evolution in the power sector, MISO believes software performance will become increasingly important. The diversity of resources offering their services into MISO’s markets is growing and the portfolio of existing resources and fuel types has shifted rapidly in recent years. In turn, resource modeling requirements are becoming more complicated, system constraints more intricate, and the volume of information greater. This paper introduces the research and development of the next generation market clearing software under the Department of Energy (DOE) Advanced Research Projects Agency–Energy (ARPA-E) project to develop high performance computer based optimization engines. The goal is to position Regional Transmission Organization or Independent System Operator (RTO/ISO) for future industry evolution.

Information Technology (IT) systems are constantly growing in everyday life, particularly in safety-critical scenarios (such as the automotive, avionics, medical, etc.) in which reliability and correctness are the main requirements that must be guaranteed.
The complexity of the information systems is increasing, and recently, in the scenario of modern systems, the Cyber-Physical System (CPS) emerged as systems in which the software component interacts continuously with the physical system in which the software operates. Compared to the dynamics of classical systems, the physical component of a CPS introduces new aspects to consider in the behavior of a system, in particular probabilistic behaviors.
The document discusses building human-based software estimation models that are accurate, intuitive, and easy to understand. It presents an approach using correlation and scale factors between estimated and actual effort. Experiments on a dataset of 178 samples show that combining correlation and scale factors into a decision tree achieves up to 93.3% accuracy. The resulting model bridges expert and algorithmic estimation methods.

B Kindilien Finding Efficiency In Mach 120408jgIpotiwon
Presentation at the 2008 Defense Manufacturer\'s Conference (DMC), Orlando, FL: The advent of finite-element modeling based systems has ushered in an era of physics-based prediction of machining operations, giving engineers new insight into designing machining strategies. Some technologies are being employed as machining process development tools. Others are being applied by companies following the tool path generation process in the computer-aided manufacturing (CAM) software systems. Further, other software technologies are evolving within the CAM software systems users currently operate, offering dramatic reductions in machining cycle times by affecting air cuts and feed rates. But users still wonder how to apply these various approaches; they puzzle over what approaches work for their shop practices. Attendees described after this presentation that they had a clearer sense of how strategic changes in machining approaches and implementation of the right technology for a given manufacturing condition can make all the difference.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.

Conclusions
18-06-2015
Configuring the best simulation’s could be a hard work for a no-expert in FEM.
HPC resources are not only needed for simulations which need a high number
of cores each one. Several multicore’s (~16) simulations are needed for running
parametric jobs (up to 16).
Troubles appears very often and they are due to different issues: mesh,
contacts definition, algorithms involved, software issues or MPI libraries.
SMEs need validate their models against real cases.
End-user prefers a GUI application and it must be flexible to incorporate new
functionalities.
Remote visualization is desirable. Best tool to visualize data depends on the
output size.
Value-added services are really needed as FORTISSIMO proposes.
This template is for the WP4xx experiments. The time for the presentation should be 45 minutes, including questions.

Another relevant scope of the project for Texas Controls, have to do with the deep study of the tensional field in flanges. As we mentioned before, typical FEM studies only take into account the final load of the bolts, given by the Engineering Codes. But due to the physical fact that Higher loads are necessary to get residual loads when, risky situations for the components, always happens during the tightening. It is very common in “on site” situations when a flange is leaking, to increase a lot the load applied, producing hidden damages in grooves and bolts. Most of the times, the better solution is to optimize the tightening procedure.
Typical failure of flanges are due fatigue situations when high stress are located in the groves where metallic gaskets are compressed. If high temperatures are involved, then Stress corrosion cracking appears.
So it is necessary to determine the minimum applied load to achieve the maximum sealing force, with no damages of grooves and bolts.
So, as I have just presented so far in the previous slides, one of our most important activities is focused in getting reliable and safe mechanical joints in the industry, so we could summarize this objective in our lemma: “Leak free Plants”
In this slide I would like to explain the problems we have to face day by day in our activity:
In our opinion, Bolted joints, in a Refinery or in a PowerGen plant, should be considered as a welded joint in many aspects. Of course there are not melted materials nor phase changes when we talk about a flanged joint…and, at a first sight, it is more simple to face a temporary joint ( for example a flange) than a welded joint, but the responsibility of the people that tighten a Flange it is the same of a welder. If this joint fails, for example in a pipe of hydrogen in a Hydrocracker, the consecuences could be catastrophic. So we have to know more about the behaviour of the elements of the flanges.
The big problems appears when we have to face the sealing of a non standard flange in critical applications.
Nowadays, Oil Refining Industry have to face problems to refine heavy oils, and, to optimize the production of lighter fractions from heavy oils, (for example tar sands refineries) This this facilities, higher pressure and higher temperatures are necessary.
Even, new technologies for energy generation as Thermal Solar Energy, needs new solutions for new problems. So, more frequently than in previous years, designers are finding solutions far away from the standards, using “ad hoc” designs. Furthermore, the optimization of the desings of Heat Exchangers, Pressure Vessels is mandatory for the Heavy Industry in Europe to better compete and to give value to their customers.
On the other hand, designer usually obviate during the design process, the tightening itself, without knowing that, in many occasions, damages in main parts occurs during the tightening process and not at the final stage of a tightened flanges.
We have detected, then, that engineers usually doesn’t take into account the tightening process itself when designing flanges of pressure vessels, and never considers the time elapsed in such process, thing that in special critical applications or in huge projects should be a critical figure to consider.
In our projects or designs, we constantly apply recommendations of entities such as the British Petroleum Institute, the Fluid Sealing Association, the European Sealing Association, ASME, API, Offshore Operators Association of the United Kingdom (UKOOA) and other research committees, and we usually get involved in mechanical simulations, finite element analysis and empirical testings on how it affects the temperature, thermal cycling, or even cryogenic conditions in the sealing products.
We have studied in many occasions the differences between applied loads and residual loads, the effects of friction when torque is involve to get a correct tightening, etc…Everything lead us to understand the interaction of different elements of the flanged joints to allow us to face the most critical jobs offering guarantees of implementation and operation of no leaking flanged joints.

The critical distances are around the groove, but the values of flexion and torsion of the flanges are important too. It is necessary to control the values around the groove to seal the assembly.

Of course there are not melted materials nor phase changes when we talk about a flanged joint…and, at a first sight, it is more simple to face a temporary joint ( for example a flange) than a welded joint, but the responsibility of the people that tighten a Flange it is the same of a welder. If this joint fails, for example in a pipe of hydrogen in a Hydrocracker, the consecuences could be catastrophic. So we have to know more about the behaviour of the elements of the flanges.
The big problems appears when we have to face the sealing of a non standard flange in critical applications.
Nowadays, Oil Refining Industry have to face problems to refine heavy oils, and, to optimize the production of lighter fractions from heavy oils, (for example tar sands refineries) This this facilities, higher pressure and higher temperatures are necessary.
Even, new technologies for energy generation as Thermal Solar Energy, needs new solutions for new problems. So, more frequently than in previous years, designers are finding solutions far away from the standards, using “ad hoc” designs. Furthermore, the optimization of the desings of Heat Exchangers, Pressure Vessels is mandatory for the Heavy Industry in Europe to better compete and to give value to their customers.
On the other hand, designer usually obviate during the design process, the tightening itself, without knowing that, in many occasions, damages in main parts occurs during the tightening process and not at the final stage of a tightened flanges.
We have detected, then, that engineers usually doesn’t take into account the tightening process itself when designing flanges of pressure vessels, and never considers the time elapsed in such process, thing that in special critical applications or in huge projects should be a critical figure to consider.
In our projects or designs, we constantly apply recommendations of entities such as the British Petroleum Institute, the Fluid Sealing Association, the European Sealing Association, ASME, API, Offshore Operators Association of the United Kingdom (UKOOA) and other research committees, and we usually get involved in mechanical simulations, finite element analysis and empirical testings on how it affects the temperature, thermal cycling, or even cryogenic conditions in the sealing products.
We have studied in many occasions the differences between applied loads and residual loads, the effects of friction when torque is involve to get a correct tightening, etc…Everything lead us to understand the interaction of different elements of the flanged joints to allow us to face the most critical jobs offering guarantees of implementation and operation of no leaking flanged joints.
The first step showed bigger displacements, the remaining steps involve adjustments over the compression. This behaviour matches with reality, where the last tightening uses smaller force over pre-tensioned material. The distribution of the stress over the flange and gasket showed a higher peak of stress over the groove zone and in the contacts between flange and gasket.
The local compression distance between the flanges determined by the prediction of the numerical model and the experimental test (Figure Local Distance ) was compared. In the graphic it can be seen how the tendency between both methodologies is the same, but the absolute values were different.
The differences are due to geometric tolerances: Positioning and surface texture. The positioning in the FEM model is perfect due to the need for a good surface contact between the flange and the gasket to properly achieve initial values for the contact algorithm. The FEM model sometimes exhibits some minor penetration between parts, which never happens in the experimental tests..
The surface texture implies roughness which is not taken into account in the FEM model. The roughness does not explain 1mm difference, but any defect in the surface of contact could generate that difference. The final results obtained by FEM methodology were validated by TEXAS because the methodology applied and the tendencies obtained were correct. The results from FEM method will be comparatives between different parameters.
