Abstract
This work investigates flow, heat and mass transfer of a chemically reacting and electrically conducting micropolar fluid over an exponentially stretching sheet in the presence of thermal radiation, viscous dissipation, suction/injection, heat source/sink and slip effects. The system of the governing partial differential equations of the fluid flow is transformed into nonlinear ordinary differential equations by applying similarity variables. The resulting equations are numerically solved via shooting method alongside fourth order Runge-Kutta integration technique. The influences of the controlling flow parameters on the dimensionless velocity, angular velocity, temperature and species concentration profiles as well as on the skin friction coefficient, wall couple stress coefficient, heat and mass transfer rates are presented through graphs and tables. Comparison of the present results with previously published work in the literature for some limiting cases shows a good agreement.
