Dear Foamer

I found there the heat flux of energy equation in openfoam is a little bit different from the text book. The energy equation in openfoam is list here:
http://cfd.direct/openfoam/energy-equation/
in which, the heat flux q=mu/Pr * Grad(e)
While the heat flux in the text book always prefer to use Fourier's Law, look like this
http://www.cfd-online.com/Wiki/Favre...okes_equations
in which the heat flux q= C_p*mu/Pr * Grad(T)

As we know e=C_v*T, so these two heat flux equations has slight difference between C_v and C_p.

Is there anyone who have noticed the difference before?

Thx a lot.
