Original Abstract

The contribution deals with the experimental and numerical modelling of the turbulent flow over an inclined backward-facing step in an open channel. The modelling was carried out in the Froude number covering the subcritical, supercritical and near critical regimes as well. The study was concentrated particularly on the development of flow separation and on changes of free surface. Numerical results obtained using the commercial software ANSYS CFX 12.0 for the two-equation SST model and the EARSM model ware compared with experimental data obtained by means of PIV and LDA measuring techniques.
