Self-induced oscillations in the shock wave flow pattern formed in a stationary supersonic flow over a double wedge

Numerical simulations of a two-dimensional supersonic flow of an inviscid perfect gas over a double wedge in the Mach numbers range 5less than or equal toMless than or equal to9, revealed the existence of self-induced oscillations in the shock wave flow pattern in a narrow range of geometrical parameters.
