Turbulent kinetic energy at wall?

I found the turbulent kinetic energy at wall was not 0,when I used no slip wall. I used three turbulence models one after one, k-epsilon,standard k-omega and k-omega SST. Wall Yplus was 1.5.
The turbulent kinetic energy at wall was error,then the turbulence viscosity and effective thermal conductivity near wall were wrong.
Someone can help me, teach me to let the turbulence kinetic energy at wall is 0.

For wall adjacent cells, the variables are all determined from the wall-models, so it is unlikely that you will find any non-physical values there.
