hello everyone,

I wish to define the solution of the turbulent kinematic energy solution near the wall, in Fluent.

My case is standard k-e with standard wall function.

From the ansys help we can see that the k-equation is solved in the whole domain including near the wall, while the epsilon adjacent to the wall is calculated from the near-wall equ with is derived from the local equilibrium hypothesis.

After the solution I found that the production of k (Gk) is zero everywhere on the wall, which is very different from the Gk equ based on the local equilibrium hypothesis.

I wish to give a definition of the k in order to force the local equilibrium near the wall. Could anybody give some advice how i can do this?

Many thanks!!
