High-Resolution Hemodynamic Analysis of a Wearable Oxygenator Using High-Performance Computing

Abstract In this paper, we study the hydrodynamics of a wearable oxygenator using computational fluid dynamics on supercomputer. computation, fiber bundle is modeled by porous medium model, and incompressible Navier-Stokes equations with K-ε turbulence model are used to flow in channels. The blood velocity, pressure, shear stress carefully studied hemolysis index NIH calculated fast three-dimensional numerical approximation method, which range 0.006 ~ 0.094 g/100L. results show that pressure loss mainly occurs area. inlet, outlet, channels have relatively high stress, may damage red cells. When rate ranges from 2.0 L/min 5.0 L/min, estimated meets applicable allowed human physiology. addition, parallel performance supercomputer, shows that, for simulation over 9 million mesh cells, it scales up 720 processors efficiency 60%.
