Experimental results are presented for the effectiveness and heat- transfer coefficient of a film cooling system in which air was used both for the film and for the freestream fluids. Injection occurred at a single tangential slot near the leading edge of the plate, and the slot size was varied. All flows were turbulent, and the injection velocities covered a range from much less to much greater than the free-stream velocity. Correlations were realized for both the effectiveness and the heat-transfer coefficient and, as in past experience with such systems, separate specifications were needed for injection velocities greater and less than the free-stream velocity.
