Energy spectrum with combustion
 
Hi,

I have made some LES calculations with combustion in OpenFOAM, thereby i calculated the energy spectrum. Unfortunately, in the inertial range the gradient is greater than -5/3. Do anyone know, if there is any influence by combustion on the spectrum? Or do anyone know some papers where the energy spectrum in connection with combustion is discussed?

Regards, Christian

Hi,Christian:
How did you get the energy spectrum, is it possible to do the two-point correlation during running?
