MHD Effect on the Couple Stress Fluid Flow Through a Bifurcated Artery

摘要

This paper aims at presenting numerical solutions for steady MHD blood flow through a bifurcated artery with mild stenosis in parent lumen with heat transfer assuming blood as couple stress fluid. The arteries design of bifurcation is referred to be symmetric about the axis of the artery and straight cylinders of limited length. The governing equations are non-dimensionalized and coordinate transformation is used to convert the irregular boundary to a well defined boundary. The resulting system of equations is solved numerically using the finite difference method. The variation of shear stress, flow rate and impedance near the flow divider with relevant physical parameters are presented graphically.
