Abstract

A theoretical analysis with numerical solutions is performed to explain the flow characteristics of an unsteady MHD Newtonian fluid along a vertical porous plate with rotation under the existence of heat and mass transfer. The governing equations of the flow pattern are converted to non-dimensional form and then solved by using finite difference scheme. The effects of different physical parameters like thermal radiation, heat source and sink, thermal diffusion and Dufour number are considered. The impact of these parameters on the fluid velocity, temperature and species concentration is de picted in the form of numerical results and graphical presentations. The current results are compared with the previously published ones and they confirm the correctness of the numerical method. The primary velocity of the fluid increases when the value of rotation parameter increases and the secondary velocity decreases in the same case.
