A Thorough Description Of How Wall Functions Are ...

Nowadays turbulence models are heavily used when doing CFD simulations. However, some mature turbulence models such as k-"are only valid in the area of turbulence fully developed, and don’t perform well in the area close to the wall. In order to deal with the near wall region, two ways are usually proposed.

Modeling Turbulent Flows Introductory FLUENT Training

The k–ωTurbulence Models The k–ωfamily of turbulence models have gained popularity mainly because: zThe model equations do not contain terms which are undefined at the wall, i.e. they can be integrated to the wall without using wall functions. zThey are accurate and robust for a wide range of boundary layer flows with pressure gradient.
