摘　　要：利用CFD方法对一种轴流式涡轮的内流场作了详细的三维紊流数值模拟。分析不同叶片结构对流场的影响情况。试验表明改进后的扭曲叶片涡轮比直叶片涡轮的水力性能高,从而验证了CFD软件是一种很有效的流体模拟软件,对改进涡轮的机械性能指明了途径。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.
