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.
