Unsteady Magnetohydrodynamic Convective Flow of a Nanoliquid via a Radially Stretched Riga Area via Optimal Homotopy Analysis Method

Abstract

This article presents the investigation of the mechanism of mass and heat transport of an unsteady incompressible electrically conducting viscous convective nanoliquid through a radially stretching Riga plate with viscous dissipation, velocity slip, Brownian motion, Thermophoresis parameter, and first-order chemical reaction. The optimal homotopy analysis technique has been utilized to compute the solutions for the differential equations system after using the similarity variables to the governing flow equations. For physical clarification, the acquired outcomes are illustrated graphically and also in the form of tables. These graphs and tables are used to exhibit physical quantities, namely, Sherwood number, skin friction coefficient, concentration, Nusselt number, temperature and velocity. One of the significant outcomes of the current scrutiny is velocity profile improves for rising values of Hartman number, and this investigation finds several applications in various fields of automobile industries and engineering.
