UDC 533.6.011

Transonic flow past a step located on the lower wall of 
a channel and modeling the airfoil is considered. The stability of 
stationary flow to small changes in the Mach number at the outlet 
of the channel is investigated numerically. The existence of special 
regimes in which flow is unstable, i.e., insignificant perturbations 
of the boundary conditions cause a qualitative change in its structure, 
has been established.
