Non-Newtonian effects of pulsatile blood flow in a realistic bypass graft geometry
Original language description
The study is focused on mathematical modelling of pulsatile blood flow in a patient-specific aorto-coronary bypass model with individual graft. Blood is considered to be an incompressible non-Newtonian fluid, whose behaviour is described by the macroscopic Carreau-Yasuda model. The numerical solution of the non-linear system of incompressible Navier-Stokes equations is based on the three-stage fractional step method and the cell-centred finite volume method formulated for hybrid unstructured tetrahedralgrids. Since patency and long-term performance of all implanted bypass grafts is closely related to hemodynamics, all obtained results are analysed and discussed with the help of several significant hemodynamical wall parameters such as cycle-averaged wall shear stress and oscillatory shear index.
