MHD Flow of Casson Nanofluid Over An Inclined Porous Stretching Surface

Abstract

This article aims to examine the unsteady hydromagnetic flow of Casson nanofluid over an inclined permeable stretching surface using Buongiorno model. The influences of velocity slip, thermal slip, concentration boundary condition of Brownian, and thermophoresis diffusion coefficients are examined. Similarity transformations are used to transform the governing flow equations into system of nonlinear ordinary differential equations. Using the Runge-Kutta $4^{th}$ order method along with the shooting technique, these equations were numerically solved. The effect on flow variables of dissimilar parameters such as chemical reaction parameter, Soret number, radiation parameter, Casson nanofluid parameter, Brownian motion parameter, and thermophoresis parameter was examined. Investigation shows that the nanoparticle concentration decreases by increasing chemical reaction parameter and rises by increasing the Soret number. In addition, the mass transfer rate decreases with rising inclination angle and chemical reaction parameter, whereas it increases with an increasing Brownian motion parameter.
