stabilize detached bow shock in transonic flow

I'm trying to capture a stabilized detached bow shock in transonic flow(M=0.8). The choking Mach here is 0.84 based on area ratio. But what I found is that the bow shock appears at the beginning of the simulation(500 iterations) and then it moves upstream, changes BC at inlet which results in lower Mach than what I set based on total pressure inlet and static pressure outlet.
Any help on it. I even decreased M=0.7 at inlet and it still has this problem....Should i use gradient adaptaton for mesh or change solution method(QUICK, 3rd order)? I'm using k-w SST in order to capture vortex shedding behind. Y+ is 0.7 more or less. |
