Effect of Permeability on Micropolar Fluid with Nanoparticles Flowing Through a Core Region in a Stenosed Artery
摘要
The flow of mixed two-layered, micropolar fluid comprising nanoparticles across a permeable stenosed artery is examined through a theoretical modeling. In a stenosed artery, the fluid flow going through two regions (specifically, the Peripheral and Core) is considered to be most illustrated by a two-layered model. The fluid in the peripheral layer is a Newtonian fluid, whereas the micropolar fluid containing nanoparticles in the core region performs as a non-Newtonian fluid. The closed expressions of flow characteristics, like axial velocity profile, flow resistance, shear stress, temperature profile and concentration distribution are found to determine the governing equations using Homotopy Perturbation Method with the assumption of mild stenosis. The significance of flow properties on flow conformation, wall shear stress and velocity profiles are discussed graphically. A remarkable conclusion is that, the axial velocity profile with the increase of local nanoparticle Grashof number
