A detailed study of the heat transfer for tangential air injection through a single slot into a turbulent boundary layer on a flat plate is presented; the results apply to a specific slot size, one injection rate, and a fixed free-stream velocity. Boundary-layer velocity and temperature profiles for a number of positions downstream from the point of injection are presented as well as plate-temperature distribution and heat-transfer data for adiabatic and constant heat input-wall boundary conditions.
