ELECTROOSMOTIC FLOW OF MICROPOLAR NANOFLUID THROUGH A NON-DARCY POROUS MEDIA WITH VON NEUMANN STABILITY CONDITION

Abstract

This study investigates the action of time-periodic temperature and nanoparticle concentration divergence on electroosmotic micropolar Eyring-Powell nanofluid flow through a non-Darcy porous medium and over an infinite vertical plate. The effects of viscous and Ohmic dissipation, heat source, thermal radiation, Dufour trait, and chemical reaction are considered. The complicated system of differential equations which governs the problem is transformed into a system of nonlinear algebraic equations by using the finite difference method. Numerical results for the velocity, microrotation velocity, temperature, and nanoparticle concentration distributions, as well as the skin friction, reduced Nusselt number, and Sherwood number, are obtained. It is noted that the velocity becomes greater with an escalating Helmholtz-Smoluchowski velocity. Meanwhile, it elevates when rising in chemical reaction order. The enriching in thermophoresis parameter causes a dwindling influence on the nanoparticle concentration while also causing an increase in temperature. This study is significant in many diverse medical implementations as nanoparticles are utilized in the treatment of cancerous tumors.
