DEFORMATION OF THE WALL OF THE ARTERY WITH TIME-DEPENDENT STENOSIS DUE TO PULSATILE FLOW OF BLOOD

Abstract

Investigation has been carried out to see how the presence of a growing stenosis affects the deformation of the wall of an artery in the pulsatile flow of blood. The expressions for the resulting deformations in the radial and axial directions were obtained. From analysis of these results, we noted that at the beginning of the growth of the stenosis, its effect on the deformation of the wall was minimal but that it increases subsequently until it assumes the same alarming destructive level that had earlier been reported, Katiyar and Mbah (7). However, the gradual growth of the stenosis distorts the flow characteristics more as compared to the situation where the maximum height of the stenosis had been attained. Detailed analysis of the results obtained is as contained in the body of this work.
