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.

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.

This book was released on 1978 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the Phase I ERDA High-Temperature Turbine Technology (HTTT) Program was to provide a ''Program and System Definition'' of the three-phase program which would culminate in the testing of a Technology Readiness Vehicle (TRV) at the end of a six-year period. The TRV is designed for use in a combined cycle using coal-derived fuels at a firing temperature of 2600°F; growth capability to 3000°F is projected. The Phase I results reported are based on a 2600°F gas turbine burning coal-derived fuels. The following major areas are covered: overall plant design descriptions; systems design descriptions; turbine subsystem design; combustor design; phase II proposed program; and phase III proposed program. Details regarding final results of each of these areas are presented. It is concluded that the water-cooled gas turbine in combined cycle has been shown to be capable of extremely attractive levels of performance, both in terms of efficiency and specific output. Coupled with the ability to tolerate a wide range of coal-derived fuels with minimum fuel treatment, an extremely attractive system is presented for the generation of electric power. Future technology development of the high-firing-temperature water-cooled gas turbine is expected to result in the commercial introduction of this concept in combined cycles by the late 1980's or early 1990's.
