Hi everyone,
i've been trying to simulate the supersonic ciompression ramp flow on fluent. Although i was able to get the steady(mean) values of the parametes (pressure, etc) right, i'm unable to replicate intermittent pressure signal near the compression corner (shock/BL interation).
till now i've tried using the spalart allmaras model only.

I wonder if anyone here has ever tried it before could help me with this.

thanks
abhishek.

Hi
The problem with spalart allmaras is that it is 1 equation so it have big problems to accomodate with high gradients
try using density based solver (in place of pressure based)

hey sophie! thanks for replying. All this time i've been using density based SA model only. i guess RANS would do better! I'll try that now.
