SINOPSIS
Heat transfer in recirculating flow without buoyancy or mass transfer through the surface was studied by numerical simulation for the case of separating and reattaching flows downstream of a backward-facing step. Two-layer k-ε models with modified wall functions were used. A modification was proposed for Johnson and Launder's sublayer Reynolds number. The computer results are compared with experimental data obtained earlier. Good prediction was obtained on relatively draft grid.
