Enhancement of Full Coverage Film Cooling Effectiveness with Mixed Injection Holes

International journal of turbo & jet-engines, 2018
In the present work numerical study of full coverage film cooling on an adiabatic flat plate is carried out. Cooling performance of three configurations of cylindrical holes is studied with downstream injection, upstream injection and mixed injection. In

Improvement in Film Cooling Effectiveness Using Single and Double Rows of Holes With Adverse Compound Angle Orientations

Journal of Thermal Science and Engineering Apllications, 2018
Three-dimensional Reynolds-averaged Navier–Stokes equations with shear stress transport turbulence model are used to analyze the film cooling effectiveness on a flat plate having single row of film hole involving cylindrical hole (CH) and laidback hole

New Techniques for Measuring Film Cooling Effectiveness

Journal of Heat Transfer, 1975
Techniques to measure local film effectiveness distributions on large-scale models of turbine blade and vane sections were developed for use in subsonic, room-temperature wind-tunnel environments. Highly detailed film cooling effectiveness distributions were obtained on near-adiabatic, cast rigid foam test models using infrared radiometer scanning ...

Analytical Studies of Transient Film-Cooling Effectiveness

1977
Abstract : An analytical model has been developed for two problems of gun barrel cooling: a. film cooling with wear reducing additives and b. liquid film cooling. The governing equations were derived from an integral method and the solutions of the film-cooling effectiveness were obtained by application of the characteristic method.
