AbstractA mathematical model is presented for the computation of two-dimensional, turbulent and recirculating flows over bluff bodies, which are separated from nearby walls with a relatively small clearance. The model comprises elliptic, two-dimensional differential-equations expressing mass conservation, momentum balance and the transport of two turbulence properties.The model is applied to predict different flows and the computed flow patterns are displayed and investigated. Comparison is made against experimental measurements available for these flows, and good agreement is generally revealed.
