Characteristic-Based Volume Penalization-Imposed Wall Function Method for Turbulent Boundary Layer Modeling
O. V. Vasilyev,

Abstract:A method to approximate near-wall boundary conditions for the compressible Reynolds-Averaged Navier–Stokes equations is proposed. The differential formulation to match the external and the wall function solutions is reformulated in a form of the generalized characteristic-based volume penalization method to model the transfer of the shear stress from the outer region of the boundary layer to the wall. The exchange location is specified implicitly in terms of a localized source term in the boundary layer equati… Show more
