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.
