Near wall treatment for ke model
Hi, I have question abt ke model with near wall treatment. Is this possible? and if yes then in which circumstances? I know that fluent have already this type, but why I am wondering is that ke model starts from log layer (I have also doubt abt that) then why ke model should have near wall treament option? bcoz ke model is one type of turbulent core model? thanks

Re: Near wall treatment for ke model
isn't near wall treatment just enhanced heat transfer calculations?

Re: Near wall treatment for ke model
The key phrase you are looking for here is "low Reynolds number" or "lowRe" turbulent models. They modify the terms in the kepison model equations so that you can use the equations all the way up to the wall. Empircal dampening functions are added or modify the equations (mostly the epsion eqn) so that the equations are asymptotically consistent with the nearwall behavior. Wilcox's book Turbulence Modeling for CFD has a good introduction to some of the first generation low Re models. They have improved since that first generation, but they have also become much more complex.

I thought the best low Re kepsilon model was the RNG version.
