Download or read book Effects of Shocks on the Unsteady Heat Transfer in a Film Cooled Transonic Turbine Cascade written by and published by . This book was released on 2001 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental program was performed to study the effects of high strength shocks on the film cooling heat transfer in a transonic turbine blade. Shocks stronger than seen in actual engines were generated by a shock tube and directed to pass into the cascade upstream of a linear set of blades. The results indicate that the increased strength of the shocks do not disrupt the boundary layer on the blade. Therefore, the heat transfer is still predictable by the methods determined for lower strength shocks, as reported in the attached two papers (presented in Munich during this research program). As a transition to work on high free-stream turbulence effects, initial results for a blown grid were obtained in low speed flow. The corresponding report is attached, but has not yet been published.

This book was released on 1998 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research program was conducted to study the effects of steady and unsteady shock impingement on the film-cooling heat transfer turbine blades. The objective of the program is to improve the fundamental physical understanding of how these unsteady phenomena affect the film-cooling heat transfer under simulated thermal and flow conditions typical of real turbine engines. The experimental program is being conducted in the Virginia Tech heated, transonic turbine cascade tunnel. Both steady and unsteady shocks were investigated: the steady shock originates from the trailing edge of the blade and impinges on the suction surface of the adjacent blade; whereas the unsteady shock(s) are generated from a shock tube and pass into the cascade upstream of the blades to simulate the interaction of a moving shock from the upstream stationary nozzle guide vane on the downstream rotating blade row. The blade geometry and film-cooling hole pattern were designed by GE Aircraft Engines.

This book was released on 2012-11-27 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive reference for engineers and researchers, Gas Turbine Heat Transfer and Cooling Technology, Second Edition has been completely revised and updated to reflect advances in the field made during the past ten years. The second edition retains the format that made the first edition so popular and adds new information mainly based on selected published papers in the open literature. See What’s New in the Second Edition: State-of-the-art cooling technologies such as advanced turbine blade film cooling and internal cooling Modern experimental methods for gas turbine heat transfer and cooling research Advanced computational models for gas turbine heat transfer and cooling performance predictions Suggestions for future research in this critical technology The book discusses the need for turbine cooling, gas turbine heat-transfer problems, and cooling methodology and covers turbine rotor and stator heat-transfer issues, including endwall and blade tip regions under engine conditions, as well as under simulated engine conditions. It then examines turbine rotor and stator blade film cooling and discusses the unsteady high free-stream turbulence effect on simulated cascade airfoils. From here, the book explores impingement cooling, rib-turbulent cooling, pin-fin cooling, and compound and new cooling techniques. It also highlights the effect of rotation on rotor coolant passage heat transfer. Coverage of experimental methods includes heat-transfer and mass-transfer techniques, liquid crystal thermography, optical techniques, as well as flow and thermal measurement techniques. The book concludes with discussions of governing equations and turbulence models and their applications for predicting turbine blade heat transfer and film cooling, and turbine blade internal cooling.
