Abstract | Circulating flow patterns of water in open channels are investigated by using depth-averaged two-dimensional numerical model and hydraulic model experiments. In the first part of the work, the numerical computation are used to investigate the effect of individual parameters, e.g . , effective stresses, entrance velocity, depth , boundary condition, etc., on the flow patterns. The configuration of the model is changed in order to examine its effect on circurating flow patterns. It has been found that (i) the effective stresses are important for the occurence of circurating flow ; (ii) in channel pool configuration, the circurating velocities increase with an decrease of pool length; (iii) in numerical model , the circurating flow can be generated on a smooth bed , while the bed resistance is negligible. In the second part, the experiment is performed on a flat-bed channel pool model using three different discharges. The flow pattern from experimental results agree with numerical results. |
