turbulence flux closure for heat transfer -- CFD Online Discussion Forums

April 29, 2013, 15:39	turbulence flux closure for heat transfer	#1
alinik Senior Member ali Join Date: Oct 2009 Posts: 318 Rep Power: 17	Guys, I am looking for some documentation regarding "anisotropic diffusion" model for turbulence flux closure for heat transfer in CFX. By default CFX uses "eddy diffusivity" model to correlate the reynolds heat flux to reynolds stress. This "anisotropic diffusion" model is available only for some of the turbulence models and I could not find any mathematical description of this model, not even in CFX documentation. Does any body know about these formulations? Thanks
