Abstract
Numerical simulations of pulsatile flow have been largely applied in the field of hemodynamics to analyze the behavior of blood flow within a vessel. The present work applies these methodologies for simulating the effects of pulsatile flow in a bifurcated geometry. The simulations are performed for a general incompressible Newtonian fluid using an open source CFD package in both steady and transient regimes. A large region of recirculation is observed in the steady flow whereas the pulsatile case attenuates these variations of velocity at the bifurcation location due to the time-dependent velocity sinusoidal wave frequency.
