Compound Wall Treatment for RANS Computation of Complex Turbulent Flows and Heat Transfer

Abstract: We present a generalised treatment of the wall boundary conditions for RANS computation of turbulent flows and heat transfer. The method blends the integration up to the wall (ItW) with the generalised wall functions (GWF) that include non-equilibrium effects. Wall boundary condition can thus be defined irrespective of whether the wall-nearest grid point lies within the viscous sublayer, in the buffer zone, or in the fully turbulent region. The computations with fine and coarse meshes of a steady and pulsating… Show more

“…The method blends integration to the wall with equilibrium wall functions [30]. The planar channel flow is very well predicted for Re τ = 395 on a fine mesh, with no evidence of a log-layer mismatch.…”

“…This method allows to cover all + values, even those falling into the critical buffer region (5 < + < 30). In this study, the compound wall treatment (CWT) approach, proposed by Popovac et al [7], is adopted to define the wall boundary conditions of the turbulent variables. The general form of CWT, for any flow variable , is given by:…”
