Dear friends,
I am simulating compressible fluid (M > 2) in a cylinder. Could you give me some advice on which turbulent model I should choose? Thank you in advance. Best Regards Eric |

Rotating? Single-phase? Wat is the data you need (heat transfer)? etc etc. You need to give some more information, but you can start with the SST model.

Many thanks.
About my model: No rotating. Single-phase Static pressure on the wall is needed. |

SST will do. Just make sure you use a high definition schema and good resolution near shock waves as that will mostly determine your pressure profile.

Thank you. Mr. Bart.
In your comment, Does "a high definition schema and good resolution" mean that I should use "High resolution"? |

That means a fine grid (for good shock resolution) and a high resolution schema indeed.
