| Abstract: | This thesis carried on the detailed computation simulation for the internal flow field of a kind of turbine by the method of CFD. The thesis emphasized to analyze the influence of the blade structure to the internal flow field at the same case, and got the optimum blade structure. The experiment had indicated that the twist blade turbine was higher than the straight blade turbine in water power performance, it has confirmed the direction for the performance prediction and the structure improvement of turbine. |
