Abstract
This study investigates the mass transfer and chemical reaction effects on unsteady MHD flow nonNewtonian fluid with pressure gradient. Here, both the upper plate and the bottom plate are stationary while the pressure gradient is varying, since the flow is poiseuille. Solutions for momentum and concentration equations are obtained by the He-Laplace scheme. The effect of various flow parameters controlling the physical situation is discussed with the aid of graphs. Significant results from this study, show that both the velocity and concentration fields decrease in magnitude with the increase in Schmidt number and chemical reaction parameter. Furthermore, the velocity of the fluid increases significantly with increase in pressure gradient parameter. The results of this work are applicable to industrial processes such polymer extrusion of dye, draining of plastic films etc.
