摘　　要：基于S1/S2流面理论,给定轴面流道形状,由求解喷水推进泵初始轴面流线,以速度矩分布和叶片厚度分布为已知条件,进行用喷水推进泵反设计的方法.采用Fortran语言编程,实现了喷水推进泵的叶轮及后置导叶设计.通过三维数值模拟,讨论了基于不同速度矩设计对喷水推进泵的效率、扬程的影响,并分析抗汽蚀性能.Based on the theory of S1 and S2 stream surface, given the impeller shape, we solve the initial axial medicinal streamline of water jet pump by singularity method. Taking the angular moment and the blade thick- ness distribution as known conditions, a computer code is written in Fortran language to design the impeller and diffuser. By three-dimensional numerical simulation, the efficiency, head, and export power of different impellers designed on different angular moment distributions are discussed, and the anti-cavitation performance is ana- lyzed.
