This book was released on 2002 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation This is Volume 1 of five volumes that comprise the proceedings of the June 2002 conference, sponsored by the International Gas Turbine Institute (IGTI), a technical institute of the American Society of Mechanical Engineers. The purpose of the conference was to facilitate international exchange and development of educational and technical information related to the design, application, manufacture, operation, maintenance, and environmental impact of all types of gas engines. With an emphasis upon the need for more efficient, cleaner, and more reliable gas turbines, the approximately 130 articles cover various technical aspects of aircraft engines; coal, biomass, and alternative fuels; combustion and fuels; education; electric power; and vehicular and small turbomachines. There is no subject index. Annotation c. Book News, Inc., Portland, OR (booknews.com).

Download or read book A Study of Film Cooling Downstream of One and Two Rows of Holes Oriented in Spanwise Normal Planes written by and published by . This book was released on 1992 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental results are presented which describe the development and structure of flow downstream of a single row and two staggered rows of film- cooling holes with compound angle orientations. With the configuration studied, holes are inclined at 90 degrees with respect to the test surface when projected into the streamwise/normal plane, and 30 degrees with respect to the test surface when projected into the spanwise/normal plane. Within each row, holes are spaced 6.0 hole diameter apart in the spanwise direction which gives 3. Od spacing between adjacent holes for the staggered row arrangement. Also presented are plots showing the streamwise development of injectant distributions and streamwise development of mean velocity distributions. Spanwise averaged values of the adiabatic film-cooling effectiveness depend mostly on four parameters: hole angle orientation, spanwise hole spacing, number of rows of film-cooling holes (one or two), and blowing ratio. Spanwise averaged values of the adiabatic film-cooling effectiveness are generally greatest at low x/d and decrease with increasing x/d values for any given blowing ratio. Spanwise averaged effectiveness values decrease with blowing ratio for x/d less than 40 except for data for m=2.5. This trend generally reverses itself at higher x/d values. Spanwise averaged isoenergetic Stanton number ratios range between 1.0 and 1.5 and show little variation as x/d increases for each value of blowing ratio, however for each x/d, values increase with increasing blowing ratio. Compound angle injection, film cooling, turbulent boundary layer.

This book was released on 1953 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various parts of aircraft propulsion engines that are in contact with hot gases often require cooling. Transpiration and film cooling, new methods that supposedly utilize cooling air more effectively than the conventional convection cooling, have already been proposed. The present report presents material necessary for a comparison of the cooling requirements of these two new methods with conventional convection cooling. Correlations that are regarded by the authors as the most reliable today are employed in evaluating each of the cooling processes.

Available in PDF, EPUB and Kindle. Book excerpt: Full-coverage film cooling is investigated both experimentally and numerically. First, surface measurements local of adiabatic film cooling eeffectiveness and heat transfer augmentation for four different arrays are described. Reported next is a comparison between two very common turbulence models, Realizable k-[epsilon] and SST k-[omega], and their ability to predict local film cooling effectiveness throughout a full-coverage array. The objective of the experimental study is the quantification of local heat transfer augmentation and adiabatic film cooling effectiveness for four surfaces cooled by large, both in hole count and in non-dimensional spacing, arrays of film cooling holes. The four arrays are of two different hole-to-hole spacings (P/D = X/D = 14.5; 19.8) and two different hole inclination angles ([alpha] = 30°; 45°), with cylindrical holes compounded relative to the flow ([beta] = 45°) and arranged in a staggered configuration. Arrays of up to 30 rows are tested so that the superposition effect of the coolant film can be studied. In addition, shortened arrays of up to 20 rows of coolant holes are also tested so that the decay of the coolant film following injection can be studied. Levels of laterally averaged effectiveness reach values as high as [eta with line above]= 0.5, and are not yet at the asymptotic limit even after 20-30 rows of injection for all cases studied. Levels of heat transfer augmentation asymptotically approach values of h=h0 [almost equal to] 1.35 rather quickly, only after 10 rows. It is conjectured that the heat transfer augmentation levels off very quickly due to the boundary layer reaching an equilibrium in which the perturbation from additional film rows has reached a balance with the damping effect resulting from viscosity. The levels of laterally averaged adiabatic film cooling effectiveness far exceeding [eta with line above]= 0.5 are much higher than expected. The heat transfer augmentation levels off quickly as opposed to the film effectiveness which continues to rise (although asymptotically) at large row numbers. This ensures that an increased row count represents coolant well spent. The numerical predictions are carried out in order to test the ability of the two most common turbulence models to properly predict full-coverage film cooling. The two models chosen, Realizable k-[epsilon] (RKE) and Shear Stress Transport k-[omega] (SSTKW), are both two-equation models coupled with Reynolds Averaged governing equations which make several gross physical assumptions and require several empirical values. Hence, the models are not expected to provide perfect results. However, very good average values are seen tobe obtained through these simple models. Using RKE in order to model full-coverage filmcooling will yield results with 30% less error than selecting SSTKW.
