| Abstract: | The hydraulic moment acting around the axes of axial flow pumps is an important parameter in the design of blade-regulating equipment. The properties of the moment can be obtained from model tests and computations, Two numerical methods, finite element method and boundary integral method, are introduced. The itsulfs show that the computational moment is in agreement with the experimental one if back flow does not occur in the pump. |
