TLDR: In this article, a numerical analysis of the MHD free convection and mass transfer flow of a dissipative fluid along a vertical plate with time-dependent plate velocity, the surface of which is exposed to a constant heat flux is presented.

Abstract: This paper presents a numerical analysis of the MHD free convection and mass transfer flow of a dissipative fluid along a vertical plate with time-dependent plate velocity, the surface of which is exposed to a constant heat flux. The non-linear system of partia l differential equations is numerically solved by the implicit finite differenc e scheme of Crank- Nicolson's type. The velocity, temperature and conc entration profiles for different values of plate velocity are plotted. The influence of the buoyancy ratio parameter, dissipation number, Grashof number , Prandtl number, Schmidt number and magnetic parameter on heat and m ass transfer are discussed. It is found that, the velocity as well as temperature increases with effects dissipation number. the velocity and temper ature decreases with increases in the magnetic parameter, while concentr ation profiles increases with increases in magnetic parameter. the velocity increases as well as the temperature and the concentration decreases with i ncreases buoyancy ratio parameter. The velocity increases as well as the te mperature and the concentration decreases with increases Grashof numb er.
