Abstract
Wall shear stress (WSS) characteristics of a stenosed artery which are the important physiological parameters for the progression of the arterial diseases atherosclerosis, are studied and compared for different Reynolds numbers and different Womersley numbers. Numerical simulations of physiological pulsatile flow through a model stenotic artery are performed by finite volume method. From this study, it is revealed that the chance of formation of atherosclerosis increases with increase in Reynolds number and decreases with increase in Womersley number. The phenomenon of mass transportation across arterial wall is more in case of increase in Womersley number rather than Reynolds number. The chance of formation of atheromatous plaque will be high with higher Reynolds number and Womersley number. In the low WSS region, high magnitude of Womersley number indicates high chance of progression of the disease atherosclerosis. High magnitude of Womersley number with low Reynolds number is more dangerous for the progression of the disease in the low WSS region.
