Dynamic Performance Optimization Research of Impeller-Baffle Compound Structure Under Water

In order to improve the dynamic performance of the bionic impeller under water, this paper designs a kind of bionic impeller-baffle compound structure, builds the mechanics model of the bionic impeller-baffle mechanism underwater, analyzes its mechanics performance based on the finite volume method, and researches the influence rule of the bionic impeller mechanics performance and its fluid field under 20 kinds of baffle device in different physical parameters. The research results indicated that the bionic impeller-baffle compound structure can have a better dynamic performance under water through changing the shape design of the baffle.
