RESUMO

In the current study, effects of chemical reaction on the MHD micropolar fluid stagnation-point flow through a stretching sheet with slip and convective boundary conditions are considered. The pertinent partial differential equations are transformed into a set of nonlinear coupled ordinary differential equations which are then solved numerically by applying the differential transformation method (DTM). The effects of different physical parameters on velocity, microrotation, temperature, and concentration distributions are illustrated graphically and discussed in detail. Numerical results for the skin friction coefficient, couple stress coefficient, and Nusselt number are tabulated for various physical parameters.
