How to calculate energy dissipation
 
Hi Friends, I am doing the DNS of the round jet with axisymmetric cylindrical cordinates, i want to calculate the kolmogorov scale , for that i found in the literature to calculate the kolmogorov scale as Lk=(nu**3/epsilon)**(1/4) for calculating epsilon the formula is rho*nu*(((dhoui/dhoxj)+dhouj/dhoxi))*(dhouj/dhoxi))/rho all are favre avaraged. my doubt is how to calculate this epsilon, if any body is allready did this please help me. thankyou for ur attention.
