Investigation of MHD Casson fluid flow past a vertical porous plate under the influence of thermal diffusion and chemical reaction

Abstract

The paper presented here discloses a detailed analytical study as to how the Casson fluid flows with characteristic properties of heat and mass transfer in an unsteady convective magnetohydrodynamic environment under the influence of thermal diffusion and chemical reaction. With the said characteristics, the fluid flows past over an oscillating vertical plate. The applicable partial differential equations are solved analytically using the perturbation technique and numerically using Matlab software. With the help of velocity, temperature and concentration, skin friction, Nusselt number, and Sherwood number are obtained and represented in tabular form. One of the important findings of this analysis includes that intensification in the Newtonian heating effect causes a gradual downfall in the rate of heat transfer at the plate and the concentration of the fluid decreases under the impact of a chemical reaction. Their physicochemical features have been dealt with in detail. This fluid flow model has several industrial applications in the fields of chemicals, polymers, medical sciences, and so forth.

“…Daily life is based on chemical reactions like baking, cooling of a nuclear reactor, rust, geothermal reservoirs, photosynthesis, formation of fog and its dispersion, chemical batteries, ceramics, combustion, food, digestion, the industry of hydrometallurgical, fermentation, production of polymer, washing with soap, chemical engineering, and recovery of thermal oil. [26][27][28][29][30] Chemical reactions occur everywhere and are not restricted to the lab. Nature is also a mixture of different compounds.…”

Insight into the Significance of Viscous Dissipation and Heat Generation/Absorption in Magneto-Hydrodynamic Radiative Casson Fluid Flow With First-Order Chemical Reaction

“…Recently, numerous studies have been conducted on Casson fluid under the applied external effects. Kodi et al [4] investigated magneto-hydrodynamic Casson fluid with chemical reactions and thermal diffusion past a porous surface. Goud et al [5] conducted free convection of Casson fluid employing FEM to study MHD flow under the external heat source over a vertically oscillating porous plate.…”
