Title: Two‐dimensional subcritical and supercritical open channel flow calculation using a time‐marching method
Abstract: Abstract A time‐marching method is presented for the calculation of two‐dimensional, high‐speed channel flow, including the usually neglected terms of slope and bottom friction. Time‐marching methods are potentially the most flexible means of calculating flow through geometrically complex channel passages, since they can readily deal with subcritical and supercritical flows. The adopted numerical scheme comes straight from gas flow computations in turbomachines. The flow is assumed to be fully mixed in the vertical direction, so that vertical variations may be neglected. Comparisons with other numerical solutions for various open channel configurations show that the proposed approach is a comparatively accurate, reliable and fast technique. It can be utilized for open channel designs.
