I have an observation.
The default values for Smagorinsky coefficients in compressible and in-compressible models are different. What could be the reason for that?
Compressible coefficients:
SmagorinskyCoeffs
{
ce 1.048;
Prt 1;
ck 0.02;
}

This makes up for a (Smagorinsky Coefficient) Cs = 0.053
SmagorinskyCoeffs
{
ce 1.05;
ck 0.0472;
}


This makes up for a Cs = 0.1
Regards,
Awais
