Abstract

The mathematical analysis presents the study of heat transfer and magneto hydrodynamic effects on pulsatile flow of blood through geometrically irregular arterial system, and its effects on cardiovascular disorder and arterial diseases. Considering the influence of magnetic field on the steno- tic artery, the effect of transverse magnetic field and multi-stenosis on the blood flow in blood vessels is studied theoretically. The blood flow is considered to be axi-symmetric with an outline of the irregular stenosis obtained from a three-dimensional casting of mild stenosed artery, so that the physical problem becomes more realistic from the physiological point of view. The MARKER AND CELL (MAC) and SUCCESSIVE –OVER-RELAXATION (SOR) methods are respectively used to solve the governing unsteady magneto-hydrodynamic equations and pressure-Poisson equation numerically. The present observations certainly have some clinical implications relating to magneto-therapy. It may help reducing the complex flow separations zones causing flow disorder and leading to the formation and propagation of the arterial diseases and cardiovascular disorders.
