wind-us SST-compressible
 

I was just going through the documents of wind-us, In the input data file if 'turbulence inviscid' is specified the Compressible Euler equations are solved but, if 'turbulence SST compressible' (or any other turbulence model) is specified which equations are solved? Is it RANS? or LES? I am a little confused.Can anyone please explain a little. Thank you
