Notes:
An application of the depth-integrated k-∊ turbulence model is presented for separated flow in a wide, shallow, rectangular channel with an abrupt expansion in width. The well-known numerical problems associated with the use of upwind and central finite differences for convection are overcome by the adoption of the spatially third-order accurate QUICK finite difference technique. Results show that modification of the depth-integrated k-∊ turbulence closure model for streamline curvature leads to significant improvement in the agreement between model predictions and experimental measurements.
