Computational fluid dynamics performance prediction for the hydrodynamic bearings of the ventrassist rotary blood pump.

Abstract

Finite-volume computations are described for laminar flow in the hydrodynamic bearings supporting 2 different versions of the impeller of the VentrAssist rotary pump. Pressure boundary conditions are taken from prior computations of turbulent flow in the whole pump with frictionless sliding of the impeller on the inside of the pump body. By investigating… (More)
