Abstract:
This work presents the mathematical modelling of heat and mass transfer flow in an electrically conducting micropolar power law fluid past a horizontal porous plate in the x - direction in presence of a transverse magnetic field, Hall Effect, chemical reaction thermal radiation and thermal diffusion. The non – linear partial differential equations governing the flow are transformed into ordinary differential equations using the usual similarity method and the resulting similarity equations are solved numerically using Runge – Kutta shooting method. The results are presented as velocity, temperature and concentration profiles for pseudoplastic and dilatant fluids and for different values of parameters governing the problem. The effects of magnetic field, thermal radiation and thermal diffusion on the skin friction, heat transfer and mass transfer rates are presented numerically in tabular form
