Abstract

Abstract

In order to explore the influence of bionic guide vane on the overall performance of the main pump, a new bionic structural design of guide vane is proposed in this paper by taking the scale model (1:2.5) of CAP1400 main pump as the study object, and an optimized model (the optimal solution of the bionic guide vane) is obtained by optimizing the design platform. By using the numerical method, the hydraulic performance and safety performance of the full three-dimensional model of the main pump are obtained. By comparing and analyzing the performance difference between the original model and optimized model, the following conclusions are drawn: under the design condition, the optimized model can improve the head and efficiency of the main pump by 1.7% and 1.9% respectively; the optimized model can reduce the internal flow field noise and improve the stress distribution on the guide vane surface; the optimized model has little effect on the cavitation performance of the main pump. This paper can provide a reference for the subsequent hydraulic design and acoustic prediction of main pump.
