轴流式血泵流体特性 CFD 研究
Research on fluid properties of the anxial flow blood pump based on CFD
摘要
Abstract
In the development of the axial flow blood pump ,the blood was usually taken as a New-tonian fluid .When taking into account of the existence of local artery stenosis and other geomet-ric mutation occurs ,an area with very low flow shear rate meight be produced in the arterial par-tial flow field .So the non-New tonian characteristics of blood should be considered .A model of the axial flow blood pump was established ,and the impaction of the flow and the rotate speed on the inlet and outlet of the flow field in the blood pump was analyzed through CFD as well as the influence of the guide vane on the flow field .By the drive experiment of the designed blood pump ,the output flow and pressure were measured .The results showed that the designed blood pump was consistent on the drive performance of the simulation .关键词
