Effects of hematocrit level on the oscillatory flow characteristic of blood in a stenosed artery

Poria S., De K. N., Mazumdar H. P.

Vol. 12, no 4

1103-1115

In this paper, a simple model for the oscillatory flow of blood through a stenosed artery is considered. Blood is considered throughout the whole tube (arterial) to be a suspension mainly of red ceIls. A standard distribution of the red celIs is assumed which is based on the idea that the concentration of the red celIs and hence viscosity of blood is higher towards the center of the tube. In effect, viscosity as assumed to vary radialIy. Analytical expressions for the axial velocity, the volumetric flow rate, resistive impedance and phase lag are derived. Effects of hematocrit level on these flow characteristics are discussed.
