EXPERIMENTAL INVESTIGATION OF THE SUPERSONIC FLOW OVER AN AXISYMMETRIC RING CAVITY

This paper presents the results of the experimental investigation of the supersonic fl ow over a ring cavity of rectangular cross-section on a cylindrical body with a conical tip. The evolution of the fl ow over a cavity with its continuously changing extent has been investigated. The transition zone boundaries within which both an open and a closed schemes of fl ow are possible have been determined by the parameter of the relative extent of the cavity. It has been shown that the fl ow conditions in the transition zone depend on the prehistory of the fl ow. The main stages of cavity fl ow restricuting at the transition zone boundaries have been described.
