Periodic blowing at frequencies up to 5 kHz was used to control the unsteadiness of a two-dimensional shock wave/turbulent boundary layer interaction. The pertinent incoming conditions were M∞ = 2.84, Re∞/ℓ = 6.5 × 107, and δo = 26 mm. The interaction was formed by a 24° compression corner, and the periodic blowing was introduced into the shock-induced separation bubble. Measurements of the fluctuating mass flux and wall pressure were made, and the unsteady flowfield was visualized through stroboscopic schlieren videography. By comparing this flow with the 24° compression corner flow without blowing, the effect of the unsteady shock could be examined.
