Abstract
The results are given of experimental and numerical investigations of the s tructure of how behind a shock wave discharged from open ends of round and square channels. It is demonstrated that the expansion regions arising in a flow behind a diffracted wave are characterized by a larger volume and a h igher expansion ratio than those arising in a stationary underexpanded jet with the same value of the Mach number of flow at the channel exit section.
