【摘要】 本文研究了离心叶轮内的流动及不同叶片出口角对离心泵性能的影响。在三元流动理论的基础上,编制了用流线曲率法求解离心泵叶轮流场的正命题程序。并将计算结果与不同出口角叶轮的实验结果进行了分析和比较,所得信息可为叶轮的筛选和设计方法的改进提供依据,以期改善泵的性能。更多还原

【Abstract】 This paper studies the influence of flow in centrifugal impeller and outlet blade angle on the performance of centrifugal pumps. A Fortran computer program which determines the internal flow of impeller on the basis of quasi3-D theory is presented. The numerical solution was analysed and compared with experimental results of 2B-31 type pump. The information obtained can be used to provide references for improving of design method of impeller, so as to improve the performance of centrifugal pumps.更多还原
