Pulsatile flow of blood in mild stenosis: effects of body acceleration

Abstract

This article is concerned with the analysis of pulsatile flow of blood through a stenosed artery including the effects of external body acceleration. The pulsatile flow behavior of blood in an artery under stenotic conditions subject to the pulsatile pressure gradient and external body acceleration has been studied. The effects of pulsatility, stenosis, body acceleration, yield stress and impedance have been investigated by modeling blood as a Casson fluid. It is observed that the yield stress of the fluid and body acceleration highly influenced the velocity of the fluid, shear stress, flow rate and impedance in a stenosed artery. It is interesting to note that the body acceleration enhances the flow rate and reduces the impedance
