Over- Underexpanded Supersonic Nozzle

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?
