Unsteady flow of Casson nano-blood through uneven/composite stenosis porous artery with an inclined magnetic field

Studying the flow of blood through unhealthy arteries has emerged as an important area of focus in recent years. Narrowing of the arteries (stenosis) is the most prevalent types of arterial diseases. The present work aims to explore the impact of an inclined magnetic field on the flow of blood via a stenotic porous artery with gold nanoparticles. The blood is supposed to be non-Newtonian and described utilizing the Casson model. To account for the effect of magneto-hemodynamic, a uniform inclined magnetic field is subjected to the flow of blood. A method of finite difference has been used to solve the equations governing the fluid flow with the boundary conditions. Features hemodynamic variables like as velocity, temperature, wall shear stress, flow rate and impedance resistance are determined at the stenosis's critical height for both composite and irregular stenosis. The present model has been verified by comparing it to previous work, and it is shown to be in great concurrence with the prior work.
