【Abstract】 ProE software is utilized to build the three-dimensional model of the blood pump, computational fluid dynamic (CFD) technology are used to to simulate the flow field numerically. Standard k-e turbulent model based on non-constant three-dimensional Navier-Stokes equation and the finite volume method based on non-structured grid are applied. The variation of the rotation speed and the angle of the rotating impeller is investigate to know the effect on the flow field. The investigation has important significance to the optimization of the conical spiral impeller and the flow channel.更多还原
