The effects of post-stenotic dilatations on the flow of micropolar fluid through stenosed artery with suspension of nanoparticles.

The intention of the current analysis is to examine mathematical model of blood flows through a tube with stenosis and dilatation under the influence of steady and incompressible micropolar fluid with nanoparticles. Coupled non-linear equations are solved by HPM method analytically. Effects of different physical parameters like micropolar parameter, coupling number, Brownian motion parameter, thermophoresis parameter, local temperature and nanoparticle Grashof number on flow resistance, shear stress at wall of the fluid are investigated. Effects of relevant parameters on arterial blood flow characteristics are studied through the graphs. It is seen that, the flow resistance enhances with the micropolar parameter, thermophoresis parameter, local temperature and nanoparticle Grashof number. But reduces with Brownian motion parameter and coupling number. [ABSTRACT FROM AUTHOR]
