The effect of joule heating, thermal radiation on the MHD convective Heat and Mass Transfer flow of a variable electrically conducting micro polar fluid.

Abstract

The magneto-hydrodynamic (MHD) and effect of Joule heating, thermal radiation, chemical reaction and dissipation on the convective heat and mass transfer flow of a micro polar fluid past a stretching sheet with variable electric conductivity in the presence of a magnetic field. The non-linear equations governing the flow, heat and mass transfer have been solved numerically by employing fourth order Runge – Kutta shooting method. Results are obtained for a range of Eckert number (Ec), magnetic, Joule heating, micro rotation parameter, heat source parameter, thermal radiation parameter and chemical reaction parameter. The sheet is assumed to be non-isothermal with prescribed heat flux varying with length.

Keywords: Joule heating, magnetic field, micro polar fluid, stretching sheet.
