flow angle in compressible flow

I'm simulating M=0.9 compressible flow over a cone and cylinder with flow angles. The domain is a square with 100*100mm and cone diameter is 2.2mm, placed in the domain center. In order to have flow angle, I set two velocity inlets with x,y components at the bottom and the left, two pressure outlet at the top and the right. Y+ here is about 0.7. I'm monitoring the inlet Mach to see if it's 0.9
The result I got is very wierd. Does anybody know how to explain what happens near to the bottom? Also there is no wall in this case but why it seems that the flow will be choked? Any suggestions on BC? |
