【摘要】 由叶轮机械三元流动两类相对流面理论及相对应的变分原理,应用变分有限元数值计算方法,求解泵喷射推进器的水动力特性。文中通过实际算例,求得推进器上转子和定子的力矩值和推力值,并与实验相比较,两者基本吻合,符合设计要求。更多还原

【Abstract】 Applying the theory of 3D flow on two types of relative stream-sheet in turbomachineand corresponding variational principle, the hydrodynamic characteristics of the impeller of ajet pump can be analyzed numerically. As the numerical results, the moment and the axialforce of the rotor and the stator of the impeller of aj et pump have been obtained, which arebasically coincide with the experimental values.更多还原
