Experimental results are presented for film cooling of an adiabatic plate downstream of one to ten slots (Part 1) and two to twenty rows of discrete punched louvers (Part 2) in a subsonic turbulent flow under zero pressure gradient. The adiabatic wall temperatures downstreams of the last equivalent slot were measured and correlated in terms of the flow parameters, equivalent slot number and slot spacing, and distances downstreams of the last equivalent slot.
