Wall shear stress for solid phase?
 

Hi,

Now I am thinking how to write the code in the nut or velocity wall function to link the wall shear stress for the solid phase in twophaseeulerfoam. I did not use the KTGF model(I directly changed the U and p equations for both two phases, and the turbulence model for fluid is applied). According to the fluid phase, the nut wall function is related to the walll shear stress and log-law formulations. Thus can I made some changes in the nut wall function for solid phase like above? In other words, how can I add the wall shear stress for solid phase from the source codes?

Do you have any suggestion?
