Adaptive wall functions for the v2‐f turbulence model

Adaptive wall functions for the v²‐f turbulence model have been derived for the flow over a flat plate at zero pressure gradient. These wall functions were implemented via tables for the turbulence quantities and the friction velocity u_τ. A special treatment for the ε and f boundary conditions is proposed. On fine grids (y⁺<1) this approach yields results consistent with the wall integration solution. Detailed numerical results are presented for a zero pressure gradient boundary layer and separated flow over a ramp. Copyright © 2006 John Wiley & Sons, Ltd.
