Results of an experimental and numerical investigation of tangential swept slot injection (sweep angles of 22.5° and 45°) into a thick turbulent boundary layer at Mach 6 are presented. Film cooling effectiveness, skin friction, and flow structure downstream of the swept slot injection are investigated. The data are compared with that for unswept slots, and it is found that cooling effective¬ness and skin-friction reductions are not significantly affected by sweeping the slot. Predictions of cooling effectiveness and skin friction obtained by a numer¬ical finite-difference technique agree reasonably well with experimental surface variables.
