In this paper, we have examined the behavior of unsteady flow of a viscous, incompressible and electrically conducting Casson fluid past an impulsively started vertical cylinder with variable temperature and mass diffusion in the presence of transversely applied uniform magnetic field and chemical reaction. The temperature and concentration level near the surface increase linearly with time. The governing equations of non-dimensional form of flow model have been solved numerically by using Crank-Nicolson implicit finite difference method. The velocity profile is discussed with the help of graphs drawn for different parameters like Casson fluid parameter, Prandtl number, chemical reaction parameter and the magnetic field parameter. The numerical values obtained for skin-friction, Nusselt number and Sherwood number have been tabulated. It is seen that the values obtained for velocity, concentration and temperature are in concurrence with the actual flow of the Casson fluid. The importance of the problem can be seen in the manufacturing of pharmaceutical products, coal in water, paints, and synthetic lubricants etc.
