Flow patterns, distribution of velocities and pressures, and allotment of now volumes are obtained in detail. Results show that dividingflow is very complicated.Dimensitons of the openings, shape o f the channel, and the backpressure in the channel affect the flow patterns of the dividing flow.展开更多
