Abstract

The flow structure is complex near the curved junction, in previous studies, relatively few studied tributary skew curve river and water sports is more complex due to the centrifugal force under this condition. In order to deeply understand the flow structure based on generalized model test, studied at the different of inflow angle and the ratio of discharge,the flow structure nearby curved corners junction area. Research results show that, when inflow angle is larger, effect of tributaries on the mainstream is getting stronger, vertical average velocity reaches the peak appears at the concave bank in downstream section. The more uneven the distribution of flow velocity becomes with an increase of inflow angle of the overall. When inflow angle becomes larger, Circulation intensity becomes more and more strength,the sections with the largest circulation intensity appears at the concave bank in downstream section is moving downward gradually.
