The goal of this project is to develop a CFD model of blood to predict hemolysis due to
mechanical action in biomedical blood-wetted devices. Most of the current models approximate blood as
a Newtonian fluid at high shear rates. Our work is based on numerical model developed in [1] that
modeled blood as a multiphase fluid with constant viscosity. Although successful in capturing phase
segregation (Fahraeus-Lindqvist effect), it still did not reach acceptable agreement with experimental
data in terms of damage. Gijsen et al. [2] reported significant differences between flow fields obtained by
Newtonian and non-Newtonian models of blood. The goal of this study is to introduce non-Newtonian
blood rheology to the base model and validate it with existing experimental data.
