Numerical simulation of non‐Newtonian blood flow in bypass models

The article presents the numerical investigation of non-Newtonian effects of steady blood flow in complete idealized 3-D bypass models, whose native artery is either coronary or femoral with average physiological parameters. Considering the blood to be a generalized Newtonian fluid, the shear-dependent viscosity is described by two well-known macroscopic nonNewtonian models (the Carreau-Yasuda model and the modified Cross model). The results were obtained by own developed computational software based on the pseudo-compressibility approach and on the cell-centred finite volume method defined on unstructured hexahedral grids.
