Film Cooling From Three Rows of Holes on Adiabatic, Constant Heat Flux and Isothermal Surfaces in the Presence of Variable Free-Stream Velocity Gradients and Turbulence Intensity
In this article the influence on film cooling effectiveness of injection from rows of holes into free streams regions with favorable, zero and adverse pressure gradients and turbulence intensities of 0.02 and 0.09 are shown. The effect of the presence of rows of holes on heat transfer from a surface is shown and the increase of heat transfer due to injection through the rows of holes for both isothermal and constant heat flux surfaces is measured.
