Numerical solution on heat transfer magnetohydrodynamic flow of micropolar casson fluid over a horizontal circular cylinder with thermal radiation

Abstract

This paper focuses on the numerical solution for magnetohydrodynamic (MHD) flow of micropolar Casson fluid with thermal radiation over a horizontal circular cylinder. The nonlinear partial differential equations of the boundary layer are first transformed into a non-dimensional form and then solved numerically using an implicit finite difference scheme known as Keller-box method. The The effects of the emerging parameters, namely Casson fluid parameter, magnetic parameter, radiation parameter and micropolar parameter on the local Nusselt number and the local skin friction coefficient, as well as the temperature, velocity and angular velocity profiles are shown graphically and discussed. The present results of local Nusselt number and the local skin friction for viscous fluid are found to be in good agreement with the literature.
