Wall Function
 

Hi everybody,

I have some question about wall function:

1. I am studying about wall function. According to following link, Does usage of Wall Function decrease number of grid on the CFD model?
When It is used wall function, Are "viscous sublayer and buffer layer" neglected at computations?
I want to use K-e model (high Re turbulence model).

2. What is scalable wall function that expressed in following Post?

Where does this option in Fluent? If someone can, please place useful links about scalable wall function.

Thanks,

Best,

Amir
