Název v původním jazyce

Non-Newtonian effects of blood flow in complete coronary and femoral bypasses

Popis výsledku v původním jazyce

A numerical investigation of non-Newtonian steady blood flow in a complete idealized 3D bypass model with occluded native artery is presented in order to study the non-Newtonian effects for two different sets of physiological parameters (artery diameterand inlet Reynolds number), which correspond to average coronary and femoral native arteries. Considering the blood to be a generalized Newtonian fluid, the shear-dependent viscosity is evaluated using the Carreau?Yasuda model. All numerical simulationsare performed by an incompressible Navier?Stokes solver developed by the authors, which is based on the pseudo-compressibility approach and the cell-centred finite volume method defined on unstructured hexahedral computational grid. For the time integration, the fourth-stage Runge?Kutta algorithm is used.
