A two-layered blood flow model of Bingham type non-Newtonian fluid

Das K., Jana S.

International Journal of Applied Mechanics and Engineering

2012

Vol. 17, no. 1

17-26

In the present paper, a two layered blood flow model through a cylindrical tube of a Bingham type non-Newtonian fluid is considered. The relative coefficients of viscosity for peripheral and core layer are determined and their nature is shown graphically for different values of the maximum hematocrit, shape parameter, etc.

A mathematical model for blood flow through straight artery of slightly non-circular cross-section

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

International Journal of Applied Mechanics and Engineering

2009

Vol. 14, no 1

261-275

In this paper, a model is presented for investigating some hydrodynamic characteristics of blood flow through a large arterial vessel of slightly non-circular cross section. The viscosity of blood is assumed non-uniform due to a distribution of erythrocytes (red cells). The effects of such variation of viscosity on the hydrodynamic flow characteristics, e.g., velocity profiles, volumetric flow rate and shear stress distribution are investigated. These characteristics are then compared with the similar results obtained for the case of blood flow through the corresponding tube of circular cross section.
