Maybe this can help. This is part of Gutierrez Marcantoni's great work on  comparing different OpenFOAM supersonic solvers.

I used the information and conclusions of this paper in rocket engine simulations obtaining fair results.

Hope it helps!

Grazie Franco!

I'll follow those discussions, thank you very much.

Chinese journal of Aeronautics have one paper on Hypersonic flow using OpenFOAM based on densityTurbo solver
