Abstract
An optimization method for centrifugal or mixed-flow pump impeller was proposed. The blade was indirectly parameterized using the angular momentum distribution and calculated by inverse design method. The design variables were separated into two categories: the meridional contour design variables and the blade design variables. Firstly, the blade shape was optimized using genetic algorithm and the meridional contour remained constant. The ANN techniques with the training sample data schemed according to design of experiment theory were adopted to build the response relation between the blade design variables and the impeller performance. Then, based on ANN approximated relation between the meridional contour design variables and the impeller performance, the meridional contour was optimized. This approach could be used to optimize the impeller, including the 3-D blade and the meridional contour, and fewer variables and less time were required. An optimized impeller in a mixed-flow pump, with the head and the efficiency were treated as objective functions, confirms the validity of this newly proposed method.
