Double Population Lattice Boltzmann Model for Magneto-Hydrodynamic Blood Flow in Stenotic Artery
Pages 130 - 141
Abstract
Atherosclerosis, which refers to a reduction in vessels diameter due to fatty deposits, is considered as the main cause of heart attacks, strokes, and peripheral vascular disease. The malfunctioning of cardiovascular system is mainly related to haemodynamics. However, the magnetic properties of blood are of great interest in haemodynamics. In this paper, a double population lattice Boltzmann model is suggested to investigate magnetohydrodynamic blood flow in stenotic artery. Blood is considered as a homogeneous fluid with magnetic properties. The rheological behavior of blood is presented by Carreau-Yasuda model. Blood flow is considered as incompressible and laminar. The vessel walls are assumed to be rigid. The proposed lattice Boltzmann model is found to be accurate, stable and effective. Findings are presented in terms of streamlines, velocity and wall shear stress profiles, based on a variety of parameters, including Reynolds and Hartmann number. The results show that the increase in magnetic intensity causes a considerable decrease in velocity and recirculation zones.
