Hematocrit effects of the axisymmetric blood flow through an artery with stenosis arteries
Journal Title: INTERNATIONAL JOURNAL OF MATHEMATICS TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 6
Abstract
When the nature of blood flow changes from its usual state to a disturbed flow condition due to the presence of a stenosis in an artery. Then it has been suggested that the deposits of cholesterol on the arterial wall and proliferation of connective tissue may be responsible for the abnormal growth in the lumen of an artery. Therefore a study about the blood flow in an arterial segment having a stenosis is important because of its unusual state disturbe the flow behaviour. An axisymmetric flow of blood through a circular tube with an axially symmetric stenosis is considered. The unsteady nonlinear Navier-Stokes equations in cylindrical coordinate system governing flow assuming axial symmetry under laminar flow condition is then solved numerically so that the problem effectively becomes two-dimensional. In this investigation, we observe the effects of red cell concentration (hematocrit) on blood flow characteristics in the presence of stenosis, and it is found that the flow resistance and the wall shear stress increases with hematocrits.
