This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to a relative high thermal efficiency, the gas turbine engine has wide ranging applications in various industries today. The aerospace and power generation sectors are probably the best known. One method of increasing the thermal efficiency of a gas turbine engine is to increase the turbine inlet temperature. This increase in temperature will result in an additional thermal load being placed on the turbine blades and in particular the nozzle guide vanes. The higher temperature gradients will increase the thermal stresses. In order to prevent failure of blades due to thermal stresses, it is important to accurately determine the magnitude of the stresses during the design phase of an engine. The accuracy of the thermal stresses mainly depends on two issues. The first is the determination of the heat transfer from the fluid to the blade and then secondly the prediction of the thermal stresses in the blade as a result of the thermal loading. In this study the flow and heat transfer problem is approached through the use of computational fluid dynamics (CFD). The principal focus is to predict the heat transfer and thermal stresses for steady state cases for both cooled and uncooled nozzle guide vanes through numerical modelling techniques. From the literature, two studies have been identified for which experimental data was available. These case studies can therefore be used to evaluate the accuracy of using CFD to simulate the thermal loading on the blades. One study focused only on solving heat transfer whilst the other included thermal stress modelling. The same methodology is then applied to a three-dimensional application in which flow and heat transfer was solved for a nozzle guide vane of a commercial gas turbine engine. The accuracy of results varied with the choice of turbulence model but was, generally within ten percent of experimental data. It was shown that the accurate determination of the heat transfer to the blade is the key element to accurately determine the thermal stresses.

Download or read book Advanced Computational Methods and Experiments in Heat Transfer XII written by B. Sundén and published by WIT Press. This book was released on 2012-06-27 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containing papers presented at the twelfth in a series of successful international conferences on Advanced Computational Methods and Experiments in Heat Transfer, this book covers the latest developments in this important field. Heat Transfer plays a major role in emerging application fields such as sustainable development and the reduction of greenhouse gases, as well as micro- and nano-scale structures and bio-engineering. Typical applications include heat exchangers, gas turbine cooling, turbulent combustion and fires, electronics cooling, melting and solidification. The nature of heat transfer problems is complex, involving many different simultaneously occurring mechanisms (e.g., heat conduction, convection, turbulence, thermal radiation. phase change). Their complexity makes it imperative that we develop reliable and accurate computational methods to replace or complement expensive and time-consuming experimental trial and error work. Tremendous advances have been achieved during recent years due to improved numerical solutions of non-linear partial differential equations and more powerful computers capable of performing efficient and rapid calculations. Nevertheless, to further progress, it will also be necessary to develop theoretical and predictive computational procedures--both basic and innovative--and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. The book includes such topics as: Heat Transfer in Energy Producing Devices; Heat Transfer Enhancement; Heat Transfer Problems; Natural and Forced Convection and Radiation; Multiphase Flow Heat Transfer; Modelling and Experiments.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a wide-ranging review of the latest research and development directions in thermal systems optimization using population-based metaheuristic methods. It helps readers to identify the best methods for their own systems, providing details of mathematical models and algorithms suitable for implementation. To reduce mathematical complexity, the authors focus on optimization of individual components rather than taking on systems as a whole. They employ numerous case studies: heat exchangers; cooling towers; power generators; refrigeration systems; and others. The importance of these subsystems to real-world situations from internal combustion to air-conditioning is made clear. The thermal systems under discussion are analysed using various metaheuristic techniques, with comparative results for different systems. The inclusion of detailed MATLAB® codes in the text will assist readers—researchers, practitioners or students—to assess these techniques for different real-world systems. Thermal System Optimization is a useful tool for thermal design researchers and engineers in academia and industry, wishing to perform thermal system identification with properly optimized parameters. It will be of interest for researchers, practitioners and graduate students with backgrounds in mechanical, chemical and power engineering.
