Abstract: The article submits wall functions model “FlowVision”. The model allows simulating turbulent flows of fluid and gas over solid impermeable surfaces on different grids. Four turbulence models are considered: $k-\varepsilon$ FlowVision, $k-\varepsilon$ Standard, SST $k-\omega$ , SA. Details of implementation of turbulence models in FlowVision software are discussed. Calculations of two test cases are demonstrated.

Keywords: turbulent flow, high-Reynolds number calculations, wall functions, plate, backward facing step.
