Thermal Diffusion and Chemical Reaction Effects on a Hydro-magnetic Natural Convection Couette Flow between Two Vertical Porous Plates| Chapter 4 | Novel Research Aspects in Mathematical and Computer Science Vol. 4

 The goal of this work is to undertake an analytical analysis of a two-dimensional steady hydro-magnetic natural convective couette flow with mass transfer of a viscous incompressible and electrically conducting Newtonian fluid between two infinite vertical parallel plates. Taking into consideration the induced magnetic field, a magnetic field of homogeneous intensity is considered to be applied transversely to the flow direction. Suction and injection are applied to the plates on a continuous basis.


The nonlinear coupled differential equations are solved analytically using the regular perturbation approach with the Eckert number Ec (1 as the perturbation parameter. The coefficients of skin frictions at the walls, the rate of heat transfer (in terms of Nusselt numbers) from the walls to the fluid, and the rate of mass transfer (in terms of Sherwood numbers) at the walls are obtained in non-dimensional form, and the effects of different physical parameters involved in the problem on these fields are graphically discussed, and the results are physically interpreted.

Findings: Chemical reaction and thermal diffusion cause concentration to drop, but high molar diffusivity and low viscosity cause it to increase. The temperature of the fluid also drops owing to thermal diffusion, but rises due to chemical reactions.

Applications: The problem formulation and subsequent conclusions have applications in chemical engineering and production.
