A supersonic flow past a recess with pressure fluctuations
in the separation zone is simulated numerically. The effect
of the gasdynamic and geometric parameters determining the
flow in the recess on the character of the pressure
fuctuations is studied. Different shapes of the recess are
considered. To simulate flow in the recess kinetically
consistent difference schemes that have proved themselves
good in describing complex flows are used. Obtained results
of numerical calculations are compared with experimental
data.
