Segregated vs Coupled, High Mach number flow?
 
As titled, which one is better for High mach number( high compressibility ) flow?

Thanks

Shocks are much better resolved with the coupled solver.

Dear Jonas thank u for your advice. Now i set RNG k-e model for the high Re number flow, but the convergence is unacceptable. Do you think which turbulence model is better for high Re number outer flows? best regards
