Numerical solution of heat transfer in MHD mixed convection flow micropolar casson fluid about solid sphere with radiation effect
This study is conducted to develop a numerical solution of heat transfer in magneto-hydrodynamic mixed convection flow micropolar Casson fluid about solid sphere. The radiation effects are also considered in the energy equation. The governing momentum energy and angular momentum equations are transformed into nonlinear partial differential equations by the use of a non-similarity transformation. These equations are solved numerically subject to an appropriate physical boundary conditions using an implicit finite difference scheme known as the Keller-box method. Several parameters namely the mixed convection parameter ? , Casson fluid parameter ? ,magnetic parameter M, radiation parameter R and micropolar parameter K have been involved in the problem. The effect of these parameters on the local Nusselt number and on the local skin friction coefficient, as well as on the temperature, velocity and angular velocity profiles are illustrated graphically. The obtained results are validated with previously published available results and are found to be in good agreement.
