A MATHEMATICAL MODEL OF BLOOD FLOW THROUGH DISEADED BLOOD VESSEL

Abstract The flow of blood in two-dimensional through the constricted radially non-symmetric multiple stenosed artery is investigated in this paper. Blood is considered a Herschek-Bulkley fluid and it is characterized by the generalized form of Navier-Stokes equation. The equations of the proposed model are solved and closed from expressions for the blood flow characteristics, resistance to flow, wall shear stress at maximum depression for different points of a single loop stenosis. It is found that resistance to flow is increased as the height of stenosis increases. And wall shear stress is increased with axial velocity for increasing values of stenosis shape parameter.
