CFD multiphase modeling of blood cells segregation in flow through microtubes

Abstract

Development of a proper blood damage model is important step in future evolution of the blood wetted devices. The mentioned model on the other hand, requires an accurate blood cell segregation prediction. Blood segregation is a phenomenon when the red blood cells tend to concentrate at the bottom and center regions of the pipe, driving the platelets to concentrate at the upper wall region of the tube. In general, the segregation of the blood is found experimentally, although these experiments were found to be costly and time intensive. Development of a numerical model for blood segregation with help of Computational Fluid Dynamics has a potential to be fast and cheap alternative to the experiments.
