Low Re k-e model bound. conds

Abhijit Tilak

my problem is how to incorporate the boundary conditions rather how to specify them in case of low re k-e model. the the original paper by Launder and Sharma says that dissipation rate at wall is zero but dissipation is finite (obviously) what does this mean..since you solve through the viscous sub-layer, k is taken as zero for yplus <10. my question is should u solve for k if yplus <10 and how to give the boundary condition for e. can any body give good refrence.
