Self-oscillatory interactions of supersonic streams with cylinders, placed in open channels

Abstract

Interactions of supersonic uniform streams with cylindrical bodies, placed in open channels, are studied. Channels of rotation with the interval of cross-sectional area decreasing are considered. Two-dimensional Euler equations are solved by an implicit third order Runge-Kutta scheme. Self-oscillatory regimes are found in CFD studies at stream Mach numbers of 3 to 4.5.
