ABSTRACT

Given in this article are the results of experimental and computational research of pressure oscillations in a channel with zero air flow. The analysis was carried out at Mach numbers of incident flow MI = 0.5−4. We present the peculiarities of self-sustained oscillations that take place in a channel.
