Application of Keller-Box Method to the Heat and Mass Transfer Analysis of Magnetohydrodynamic Flow of Micropolar Fluid between Porous Parallel Walls of Different Permeability

The present work seeks to investigate the problem of stable laminar micropolar fluid flow through porous walls varying permeability. Furthermore, effect an external magnetic field is investigated. resulting solution extended analyse nonlinear differential equation heat and mass transfer in situation. velocity microrotation at channel’s entrance are assumed be those Poiseuille flow. Using appropriate transformations, governing equations transformed a system ordinary equations, which then solved using novel numerical technique based on finite difference scheme termed Keller-box method. results show that smooth straightforward method for estimating solutions complex since it simple implement. Graphs tables used explain significant parameters such as suction Reynolds number, micro rotation/angular parameters, Peclet number stream function, temperature distribution, concentration properties fluid. wall permeability longitudinal has been couple stress skin friction have also calculated. variation showing importance inertial forces comparison with viscous forces. boundary layer observed decrease when there increase number. accuracy convergence obtained applicable various physical problems, even non-linearity.
