【 摘 要 】

The heat and mass transfer in non-Newtonian fluids plays a major role in technology and in nature due to its stress relaxation, shear thinning and thickening properties. In this study, we investigated the heat and mass transfer in unsteady liquid film flow of Casson fluid in the presence of aligned magnetic field, thermophoresis and Brownian moment effects. The transformed governing boundary layer equations are solved numerically by employing shooting technique. Dual solutions are explored for Newtonian and non-Newtonian cases. The impact of pertinent parameters on the flow, thermal and concentration fields are discussed with the assistance of graphical illustrations. The reduced Nusselt number is reported and discussed through tabular results.
