Abstract

Physiological pulsatile flow in a 3D model of arterial stenosisis investigated by applying Large Eddy Simulation(LES)technique. The computational domain has been chosen is as imple channel with a biological type stenosis formed eccentrically on the top wall. The physiological pulsation is generated at the inlet of the model using the fourth harmonic of the Fourier series of the physiological pressure pulse. The flow Reynolds numbers which are typical of those found in human large artery are chosen in the present work. Transitions to turbulent of the pulsatile flow in the post stenosis are examined through the various numerical results and explained physically along with the relevant medical concerns.
