With the characteristics of curved chute,relatively high flow drop and huge discharges in the downstream reservoir spillway of Yangjiang pumped storage plant,the project problems of torrent shock wave in curved chute and flood discharge energy dissipation are relatively outstanding.

A new measure of eliminating the torrent shock wave in steep bend channel;

Based on the motion mechanism of the bend flow,first,the mathematic model is tested by the representative experimentation,then the affection of a pile wharfs with approach bridge on the bend reach of Xijiang river of Guangdong is simulated,that the especial changes of bend flow by the pile wharfs is pointed out,and the deficiency in the numerical calculation need further research.

The turbulent characteristics of bend flow are analyzed and a mathematical expression of the relative turbulent intensity along longitudinal direction is acquired.

Based on the behavior of bend channel flow, the present situation of bend channel hydraulics research at home and abroad is summarized and analysed.

Based on the generalized curved conduit flow experiment,adopting the ADV to measure and analyze the 3D velocity data,the circulation configuration in curved conduit are studied,the results of which show that the circulation configuration is different before and after the bend apex and may stratify in depth.

A generalized curved conduit flow experiment is employed to systematically study the flow characteristics and the kinematical law.

The hydraulic characteristics of curved conduit flow are one of the most interesting subjects to hydraulic researchers.
