I am using the Non-Isothermal Flow (nitf) module and I have a question on the heat transport turbulence model. In the equation given by COMSOL,
rho * Cp * dT/dt + rho * Cp * u . Grad(T) = Grad . (k Grad(T) ) + Q + Qvh + Wp
I noticed that there is a difference between Version 4.4 and Version 4.3b, with the addition of the last two terms. Then I checked the document for Kays-Crawford, what puzzles me is how the Prandtl number is invovled in the above equation. Is there a way that I can see the full equation for the above one? Also, what are the functions for the last two terms?
Thank you!
