Compressible Isotropic Turbulence
 

Hello,

I have some queries related to compressible isotropic turbulence. In most of the
computational simulations of isotropic turbulence, only microscale reynolds number and
turbulent mach number are given. But with these values, how to determine the reference
reynolds number and Mach number. And how to determine the constant A in the energy spectra, E(k)=AK4exp(-2k2/k20). Any kind of help is highly appreciated.

Loka.
