所以这里我大胆推测:所谓nut的wallfunction只是告诉OpenFOAM,我已经给构成nut的某个变量套上wall function了,记得求nut的时候注意一点。 然而,我猜错了。我所想的“一个方程用两遍”的问题似乎不存在。我所想的“提醒一下”的方式是有的,叫做“calculated” boundary condition, 然而这里的nutWallfunctions不是这么处...

Heat flux in OpenFOAM is: qDot = alphaEff| v-> f * grad(h) but i am not sure about fluent. here is the complete case set: http://cdn.anonfiles.com/1336156429443.zip Upon generating results which is comparable to fluent, one can say that OpenFOAM wall functions a...

First of all, I assume that this is a low Re number wall function, otherwise the wall shear stress is not directly connected to the velocity gradient at the wall (if this is gibberish to you, then you need to research nutkWallFunction and wall functions in general). ...
The flow near the wall was addressed using two specific wall functions: (i) the kqRWallFunction [47] for managing the turbulent kinetic energy, and (ii) the nutkwallfunction [47] for handling the turbulent viscosity, as realised in the OpenFoam framework. Finally, walls were considered ...

The reason why binomial2 and binomial blending methods exist at the same time is to ensure the bitwise regression with the previous versions since binomial2 and binomial with n=2 will yield slightly different output due to the miniscule differences in the implementation of the basic functions (i...
