Abstract

This study investigates the ow, heat and mass transfer of an electrically conducting micropolar uid over an inclined permeable surface. In the analysis, the effects of thermophoresis, Soret and Dufour, non-uniform heat source/sink as well as chemical reaction are examined in the presence of variable dynamic viscosity and thermal conductivity. The set of governing equations modelling the problem is transformed from partial to ordinary differential equations with the use of appropriate similarity transformation variables. Subsequently, Runge-Kutta-Fehlberg integration scheme cum shooting techniques is applied to yield the numerical solu- tions for the reduced equations. The findings are both displayed on graphs and tables showing the in uences of various physical parameters on the dimensionless velocity, temperature, concentration and microrotation profiles. The obtained results compared favourably with the earlier reported data in the literature as special cases of this present research. The results show that the momentum and concentration boundary layer thick- nesses fall with an increase in thermophoresis and chemical reaction parameters while the opposite occurs with a rise in the thermal conductivity parameter.
