kinetic energy spectrum of dnsFoam
I have a question about the kinetic energy spectrum of dnsFoam. The spectrum is defined as:
I didn't find this formula in literature. So, where can I find it and what is the meaning of the constants Ea and k0?
Is k0 the forced mean kinetic energy?
Another question concerns the values of UOKupper and UOKlower. Are they problem-dependent? If yes, how should they look?
