Reflected Shock Waves

VSass · June 27, 2013, 08:04

Hi all,

i'm trying to simulate a supersonic flow (Ma=1.5) over a wedge (half of it for simplicity) and i used both rhoCentralFoam and sonicFoam. When the calculated shock ange drives the shock out of the channel, everything works fine.

The problem is that, when i have reflected shocks in the channel, they don't reach a steady, converged state but the keep moving opposite to the flow (towards the inlet). After some time they occupy the whole channel.

I've tried many BCs but the shocks still move, no matter the solver.

Any suggestions would be very helpful

Thanks in advance
