CHEMICAL REACTION AND THERMAL RADIATION EFFECTS ON UNSTEADY MHD FLOW OF AN INCOMPRESSIBLE VISCOUS FLUID PAST A MOVING VERTICAL CYLINDER

In the present study, the effects of chemical reaction and thermal radiation on unsteady MHD flow of a viscous, electrically conducting and incompressible fluid mixture past a moving vertical cylinder is studied. The fluid is a gray, absorbing - emitting but non scattering medium and the Rosseland approximation is used to describe the radiative heat flux in the energy equation. The governing dimensionless coupled non - linear partial differential equations are solved numerically using finite difference method (FDM) by developing suitable codes in MATLAB. The fluid velocity, temperature and species concentration profiles have been drawn for time and various flow parameters such as Radiation parameter (N) and chemical reaction parameter ( ), and results are disc ussed.
