Results of numerical search for new self-oscillatory compressible flows are presented. Twodimensional Reynolds-averaged Navier-Stocks equations added by an algebraic turbulence model are solved by an implicit third order Runge-Kutta scheme. Interactions of supersonic jets with cylindrical bodies, placed in open tubes, are discovered to have self-oscillatory regimes. Search for unsteady flows is carried out at jet Mach numbers 1.1≤M≤1.2.
