| Abstract: | In order to reduce blood eddy-current and hemolysis, the structures of volute and outlet pipe in symmetrical centrifugal blood pump were optimized and simulated by Fluent software. The results show that the inner-trapezoidal cross-section volute with modified outlet pipe can effectively improve the performance of the blood pump, and the hemolytic predictive value can satisfy the usage requirement. |
