This article presents the heat and mass transfer characteristics of unsteady MHD flow of a viscous, incompressible and electrically conducting micropolar fluid in the presence of viscous dissipation and radiation over a porous stretching sheet with chemical reaction. The governing partial differential equations (PDEs) are reduced to ordinary differential equations (ODEs) by applying suitable similarity transformations which are then solved numerically using fourth order Runge-Kutta method. The results are depicted graphically for velocity, angular velocity, temperature and concentration profiles for various values of parameters such as unsteadiness parameter, magnetic parameter, porous parameter, thermal Grashof number, solutal Grashof number, Prandtl number, thermal radiation parameter, Eckert number, Schmidt number and chemical reaction parameter. To check the accuracy of our numerical code, comparison is made with the existing results. The influence of various parameters on skin friction coefficient, couple stress and rates of heat and mass transfer coefficients are presented numerically in tabular form.
