Numerical Solution of Micropolar Casson Fluid Behaviour on Steady MHD Natural Convective Flow about A Solid Sphere

Abstract

In this study, steady laminar 2D (MHD) natural convection flow suspended micropolar Casson fluid over a solid sphere is investigated. The governing partial differential equations are transformed into dimensionless form and then solved numerically using an implicit finite difference scheme known as Keller-box method. The behaviors of different parameters namely, Casson fluid parameter, magnetic parameter and micropolar parameter on the local Nusselt number and the local skin friction coefficient, as well as the temperature, velocity and angular velocity have been examined graphically. From graphical results, it is found that as Casson parameter increases the local Nusselt number and angular velocity profiles increase and local skin friction coefficient, temperature and velocity profiles decrease.
