Abstract
The mass and heat transfer magnetohydrodynamic (MHD) flows have a substantial use in heat exchangers, electromagnetic casting, X-rays, the cooling of nuclear reactors, mass transportation, magnetic drug treatment, energy systems, fiber coating, etc. The present work numerically explores the mass and heat transportation flow of MHD micropolar fluid with the consideration of a chemical reaction. The flow is taken between the walls of a permeable channel. The quasi-linearization technique is utilized to solve the complex dynamical coupled and nonlinear differential equations. The consequences of the preeminent parameters are portrayed via graphs and tables. A tabular and graphical comparison evidently reveals a correlation of our results with the existing ones. A strong deceleration is found in the concentration due to the effect of a chemical reaction. Furthermore, the impact of the magnetic field force is to devaluate the mass and heat transfer rates not only at the lower but at the upper channel walls, likewise.
Highlights
An inclusive computational analysis of the non-Newtonian MHD micropolar fluid flow is presented in this paper
We have considered a porous medium between the walls of the channel
The use of a porous medium plays a pivotal role in maintaining the flow, which adjusts the heat transport rate and alters the temperature distribution as required
Summary
Rashidi et al [27,28,29] presented different types of solution approximations over a porous gyrating disk and non-vertical sheet geometries for the MHD flow of a second-grade fluid They considered various analytical methods (i.e., DTM, HAM, Padé approximation, and modified DTM) for approximating the mathematical formulations of the second-grade fluids. Examined the heat source and sink impacts on the buoyant flow of micropolar liquid through a porous channel with velocity and thermal slip boundary assumptions They compared the features of the micropolar liquid with Newtonian fluid and reported that various governing thermophysical parameters exhibit a reduction in fluxes of the flow field. The graphical and tabular data have been obtained through numerical simulations of concerned constituent relations using a strongly convergent algorithm based on computer programming software
