Experimental investigation of transpiration cooling for a turbulent boundary layer in subsonic flow using air as a coolant

William E. Brunk
Oct 1957

Experiments were performed to determine the effect of injecting coolant air through a porous sintered bronze plate into a constant-area tunnel through which hot air was flowing. The boundary layer was turbulent over the porous plate for all test runs. Tests were made with either a constant coolant injection rate or a constant wall temperature.
