7 - On a new numerical approach of MHD mixed convection flow with heat and mass transfer of a micropolar fluid over an unsteady stretching sheet in the presence of viscous dissipation and thermal radiation

Abstract

In this study, we deal with the problem of unsteady heat and mass transfer of a magnetohydrodynamics mixed convection flow of a micropolar fluid over a stretching surface in the presence of viscous dissipation, chemical reaction, and thermal radiation. The governing partial differential equations are transformed into a system of nonlinear ordinary differential equations using suitable similarity transformations. The resultant system of ordinary differential equations is then solved numerically using a recently developed Spectral Quasi-Linearization Method. A parametric study illustrates the influence of unsteady parameter, magnetic parameter, Eckert number, chemical reaction and buoyancy parameters, and the micropolar parameters. The Spectral Quasi-Linearization Method is found to be very efficient and converging much faster than the bvp4c routine.
