Radiation and chemical reaction effects on unsteady MHD free convention mass transfer fluid flow in a porous plate

Objective: To study the effects of Radiation and chemical reaction on unsteady MHD free convection flow in a porous plate. Method: The problem is governed by coupled non-linear partial differential equations. The nondimensional equations of the problem have been solved numerically using Finite Element Method. Findings: The effects of governing parameters on the flow variables are discussed quantitatively with the help of graphs for the flow field, temperature field, concentration field, skin friction and Nusselt number. Novelty: The accuracy of the problem has been verified by comparing with the previous published work and the agreement between the results is excellent, which established confidence in the numerical results reported in this study. Keywords: Radiation parameter; Chemical reaction; Eckert number; heat source parameter; micro polar fluid
