仿生抗冲蚀阀芯的研究

In this paper, the bionic tamarix chinensis anti- erosion structure is adopted to increase the life of the valve spool under the erosion of the sand in the injected water. by analyzing the anti-erosion morphology of tamarix chinensis, six bionic anti-erosion structures and the different arrangements are proposed. After adopting these bionic anti-erosion structures on the surface of the valve cone that is eroded seriously, the erosion rate of each bionic anti-erosion structure is calculated by using the discrete phase model in FLUENT. Then the bionic anti-erosion structure that has the best performance of anti-erosion is chosen to add on the surface of the valve cone. At last, the parameters of the anti-erosion structure of the valve core are optimized by the optimization software ISIGHT, in order to increase the life of the water distributor.
