Optimization parameters of the heart pump design
In this paper, research of optimization parameters of continuous flow heart pump is presented. The application of centrifugal pumps as heart assist devices imposes design limitations on the geometry of the heart pump. Geometry and pump parameters affect the performance and the hemocompatibility of the heart pump. The main quality assessment factor for heart pump is the pump hemocompatibility i.e., the amount of mechanical damage caused by a pump on blood cells. Besides stagnation zones and recirculation zones, wall shear stress is parameter that is used to predict pump hemocompatibility. Second important factor is minimal volume of heart pump with acceptable anatomical fitting. Additional factors are high efficiency, performance and durability. The aim of the research is to propose the optimal design of bladeless centrifugal heart pump. The dimensionless optimization parameters of the heart pump design are derived from Navier - Stokes equation. In conclusion, dimensionless optimization parameters of bladeless centrifugal continuous flow heart pump are presented.
