I am working on the wall treatment in OpenFOAM, and as i've learned, the so called nutUSpaldingWallFunction is giving very good results in all y+ regions. I also made some calculations with it using kOmegaSST turbulence model, and as expected, it gave me very good results. But i would like to go deep with this wall treatment, and i would like to know the formulation (governing equations) of this wall function. Does anyone can help me with this? how can i find the governing equations of nutUSpaldingWallFunction in OpenFOAM?
thanks in advance
You might want to read the doctoral thesis by Dr. Eugene de Villiers(pp.80-81):

Spalding, a single formula for the law of the wall. Journal of applied mechanics. 1961.
The story is complete there.
Thanks a lot to you all,
it really helped your answers.
