ABSTRACT
We present a generalized treatment of wall boundary conditions for RANS computation of turbulent flows and heat transfer, which combines the integration up to the wall with generalized wall functions that include non-equilibrium effects. Wall boundary conditions can thus be defined irrespective of whether the grid point nearest to the wall lies within the viscous sublayer, in the buffer zone, or in the fully turbulent region. The computations with fine and coarse meshes of flows in a plane channel, behind a backward-facing step and in a round impinging jet using the proposed compound wall treatment are in satisfactory agreement with the available experiments and DNS data.
