Over- Underexpanded Supersonic Nozzle
1 Attachment(s)
Hy folks!
I'm new to OpenFoam. I try to simulate the flow behind a supersonic nozzle. Now I don't really know if the solver that I'm using is appropriate for this task or if my boundary conditions are even set correctly. I use the solver rhoCentralFoam. My boundary conditions are as follows (see the attached picture for the numbering of my boundaries): B1 : pressure fixedValue, temperature fixedValue, velocity fixedValue B2 : pressure slip, temperature slip, velocity slip B3: pressure fixedValue, temperature zeroGradient, velocity zeroGradient B4: pressure slip, temperature slip, velocity slip B5: pressure fixedValue, temperature zeroGradient, velocity zeroGradient B6: pressure symmetryPlane, temperature symmetryPlane, velocity symmetryPlane My calculation didn't work properly :( Could someone please give me some tips concerning the solver and the boundary conditions? Cheers! |
