摘要：
The results are given of experimental and numerical investigations of the total pressure across a stagnation shock in the flow C, behind a shock wave discharged from open ends of round and square channels. It is found that the loss of total pressure behind a stagnation wave before an obstacle when discharged from a square channel exceeds that in the case of a round channel. The observed effect is attributed to the fact that, when a shock wave is discharged from a square channel, the flow separation occurs at a greater angle, which is accompanied by an increase in the Mach number of the flow.
