supersonic axisymmetric cavity flow
 

hii...currently i m working on supersonic axisymmetric cavity flow for my master's thesis...i have done unsteady pressure measurements wid time step of e-07 n e-09. with the former i m getting somewat similar pressure plots as given in one of the paper i m using for validating my grids but not getting the desired frequency n wid the latter i m not getting the similar mean surface pressure plots though i got the frequency...i have tried wid 80*100 cells on cavity of depth 3mm n length 4 mm for both the cases. ...plss somebody suggest some soluton plss
