Free convection flow and mass transfer of non-Newtonian Power-law fluid over a vertical moving plate in constant heat flux

This paper presents a numerical analysis of the free convection and mass transfer flow of a non-Newtonian power-Law fluid along a vertical moving plate with time–dependent axial velocity, the surface of which is exposed to a constant wall temperature. The non-linear system of partial differential equations is numerically solved by the implicit finite difference scheme of Crank–Nicolson’s type. The velocity, temperature and concentration profiles for different values of plate velocity are plotted. The influence of the flow behavior index, Grashof number, Prandtl number and Schmidt number on heat and mass transfer are discussed. It is found that, the velocity as well as temperature increases with effects dissipation number. The velocity and temperature decreases with increases in the magnetic parameter, while concentration profiles increases with increases in magnetic parameter. The velocity increases as well as the temperature and the concentration decreases with increases buoyancy ratio parameter. The velocity increases as well as the temperature and the concentration decreases with increases Grashof number.
