    Notes: The spatially third-order accurate QUICK finite difference technique is applied to the solution of the depth-integrated equations of motion for steady, subcritical, free surface flow in a wide, shallow, rectangular channel with and without an abrupt expansion. The conservative, control-volume discretization of the equations of motion and the use of QUICK in approximating required cell and cell face average quantities is discussed. Results presented show that it is possible to obtain stable solutions for advective free surface flows without resorting to implicit numerical smoothing.

    Application of the two-equation k-∊ turbulence model to a two-dimensional, steady, free surface flow problem with separation (1985)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 5 (1985), S. 257-268

    Keywords: Turbulence Model ; Finite Difference ; QUICK ; Free Surface Flow ; Channel Expansion ; Engineering ; Engineering General

    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.
