I am having a question about the standard wall function in FLuent. The wall function in Fluent based on the Launder and Spalding wall function.

For the first node away off the wall, the production and disipation in k equation is modified based on the log law of wall. The value of epsilon is fixed.

I wonder that how the viscosity is modified base on the log law of the wall. There is no information of viscosity in Fluent. On ther other hand, The Launder - Spalding method, the wall viscosity is modified?

Thank in advance.
