摘要：
The purpose of this study is both to further optimize the structure of cross-flow turbine and to improve the turbine performance. Optimization of the turbine structure has been made by the analysis of the turbine performance with the variation of the blade angle using a commercial CFD code. The results show that inlet and outlet angles of the runner blade give considerable effect on the performance of the turbine. Pressure on the surface of the runner blade changes considerably with the variation of blade angle both at the stages 1 and 2 but relatively small change occurs for the fluid velocity of cross-flow hydraulic turbine. Recirculating flow in the runner passage causes considerable hydraulic loss by which efficiency of the turbine decreases very much. https://link.springer.com/content/pdf/10.1007/978-3-540-75995-9_140.pdf
