Abstract
MHD free convection flow of Sodium Alginate nanofluid on a solid sphere with prescribed wall temperature is investigated. Tiwari and Das’s nanofluid model is applied to analyze the influence of nanoparticles and magnetic field on a natural convective flow. Titanium dioxide (TiO2), Silver (Ag), and Graphite oxide (GO) Sodium Alginate-based nanofluid has been considered. The Keller-box method is employed to solve the transformed system of partial differential equations. The impact of Casson fluid parameter, magnetic parameter, nanoparticles volume fraction on local skin friction coefficient, local Nusselt number, temperature, and velocity are plotted and analyzed. Our graphical results revealed that the (GO)- Sodium Alginate based Casson nanofluid has the highest local skin friction, local Nusselt number and velocity profiles as compared to the other nanoparticles Sodium Alginate based Casson nanofluid.
