Improved Shiono and Knight Method for Overflow Modeling
AbstractThe current study presents an improved Shiono and Knight method (SKM) applying the complete secondary flow term that includes both the dispersion and the transverse convection components, which outspread the SKM solution. The model calibration coefficients for quantifying the secondary flow term are specified for the discrete lateral regions, defined based on the perturbation in distribution of lateral depth-averaged velocity and the boundary shear stress distribution. The inaccuracy in prediction of the SKM approach is attributed to poor secondary flow cells modeled in the interface zone. Improved SKM is adapted for laboratory and natural symmetrical and asymmetrical cross sections in both homogeneous and nonhomogeneous boundary conditions. The improved SKM has notably enhanced the precision of the prediction of depth-averaged velocity in the interface zone.
