MODELING OF MHD BLOOD FLOW IN A BALLOON CATHETERIZED ARTERIAL STENOSIS WITH THERMAL RADIATION

This article is concerned with the analysis of blood flow through arterial catheterization (widening of arteries by a balloon in the presence of mild stenosis), when blood is represented by MHD Newtonian fluid. The mild stenosis approximation is used to solve the problem. A uniform magnetic field is applied perpendicular to the porous artery. A mathematical model is developed and analyzed by using appropriate mathematical techniques. The dimensionless governing coupled, non-linear partial differential equations are solved numerically by finite difference method. This study provides a scope for estimating the influence of the problem parameters on different flow characteristics and to determine which of the parameters has the most dominating role. The study of the above model is very significant as it has direct applications in the treatment of cardiovascular diseases.
