| Abstract: | Centrifugal pump is the application of a very wide range of fluid transfer equipment,widely used as irrigation and water being transported in agriculture,the position in agricultural production is no doubt.Since the movement of fluid in the machine is very complex,and used of existing data as a pump design basis,the rational application of similarity laws had came into being.In this paper,simulated the flow field of centrifugal pump based CFD,the flow phenomena and laws of centrifugal pump were analyzed,mea... |
