Abstract
Minimizing harm to red blood cells is one of the challenges in design of blood-wetted devices. This work intended to estimate the Hemolysis Index as a measure of red blood cell damage in the DMG FA-40 arterial blood filter. The geometric model was created in SOLIDWORKS® 2018 based on direct measurements, the mesh made in ANSYS® Meshing™ 2019R1 and the flow simulation performed in ANSYS® Fluent® 2019R1 for three flow rates. The Darcy-Forchheimer law was used as the filtering element flow model. The results showed damage to decrease with flow rate and the inlet canal manifold presented as the zone with most potential damage to the red blood cells. This work suggests numerical simulation can be used for evaluating the design of blood wetted devices.
