• THE EFFECT OF CHEMICAL REACTION ON AN UNSTEADY MHD FLOW OF A ROTATING FLUID PAST A VERTICAL POROUS PLATE IN THE PRESENCE OF RADIATION

A Srisailam*

Abstract


Finite solution of the unsteady hydromagnetic natural convection heat and mass transfer flow of a rotating, incompressible, viscous Boussinesq fluid is presented in this study in the presence of radiative heat transfer and a first order chemical reaction between the fluid and the diffusing species. The Rosseland approximation for an optically thick fluid is invoked to describe the radiative flux. Results obtained show that a decrease in the temperature boundary layer occurs when the Prandtl number and the radiation parameter are increased and the flow velocity approaches steady state as the time parameter  is increased. These findings are in quantitative agreement with earlier reported studies.
