| Abstract: | On the basis of an earlier investigation of a two-dimensional combined flow, a three-dimensional local flow phenomena and its application to practical engineering are systematically investigated.Some basic characteristics of three-dimensional combined flow, such as convecting rule of flow patterns, terminal water depths, effects of unsymmetry and lateral diffusion in flows are also presented. A general formula for predicting the terminal depths has been developed, the result is deduced to a form applicable for engineering design. |
