heat transfer wall function

Aurelien Thinat · April 30, 2012, 11:12

Hi everybody,

I am looking at any information about the alphat wall functions, and more precisely the alphatJayatillekeWallfunction. Is there any article about the wall function in OF ?

I had some difficulties to stabilize a compressible k-epsilon RANS model with the alphatwallfunction. I'm working on a low reynolds mesh at walls (y+ ~ 1.5).

Hi,

Could you also post your case if it is small? currently i am also working on flat plate test case to verify alphat wall function for heat transfer problems where i have fluent results. initially i also had low reynolds grid but changed to coarse grid inorder to work with standard high reynolds compressible turbulence model.

here is my current post,
