| Summary: | Abstract
Adaptive wall functions for the
v
2
‐
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. |
