An extended κ–ϵ model (to include low‐Reynolds‐number regions) employing weighting functions is presented. Wall functions for the near‐wall zones are developed giving correct boundary values for the Shear stress and κ–ϵ. A finite element model using a penalty formulation for incompressible turbulent flow is applied to Solve a flow between two plates. Results with mesh boundaries situated in the near‐wall region and a: the wall are compared with measured values.
