Motivation & Objectives
- For medical devices with blood circulation such as ventricular assist device(VAD) and extra-corporeal membrane oxygenation(ECMO), hemolysis is a very important issue in terms of health safety
: Hemolysis is a phenomenon that the membrane of a red blood cell (RBC) is damaged by stress and then the hemoglobin is released from RBC to the plasma.
- In order to measure the level of hemolysis inside artificial medical devices, in-vitro experiments are possible but many iterations of such experiments to develop a medical device are often impractical.
: A predictive capability of hemolysis using numerical simulation has a clear advantage by relieving these limitations.
- The main objective is to develop a turbulent wall model for hemolysis to improve accuracy of hemolysis prediction.
Flow fields
- BDI comparison between using wall model and conventional numerical discretization with 16G cannula
- Comparison of the contour plots of power-law source term
: Geometric shapes of commercial blood pumps (Capiox, BP-80) are tested
< Geometry shape of Capiox >
< Power-law source term of Capiox >
