Effects of chemical reaction, Soret and Lorentz force on Casson fluid flow past an exponentially accelerated vertical plate: A comprehensive analysis

Abstract

The aim of the current study is to explore the effects of heat and mass transfer on unsteady chemically reacted Casson liquid flow over an exponentially accelerated vertical plate in a porous medium. It is assumed that the bounding plate has varying temperatures as well as concentrations in a porous medium under a uniform magnetic field. This phenomenon is modeled in the form of a system of partial differential equations (PDEs) with boundary conditions. The governing dimensionless PDEs are solved using Laplace transform method for velocity, temperature, and concentration. The impact of nondimensional parameters, which are controlling the flow like Casson parameter, Soret number, magnetic parameter, heat generation parameter, Prandtl number, radiation parameter, and Schmidt number is analyzed through graphs. The incremental values of the Casson fluid parameter lead to a reduction in velocity and discovered that for large values of the Casson parameter, the fluid is near to the Newtonian fluid. Also, the Sherwood number increases with enhancing dissimilar estimators of the Schmidt and Soret numbers. A comparison has been made with the published work (Kataria et al.) for a particular case, which was in good agreement.

Thermal and mass stratification effects on unsteady parabolic flow past an infinite vertical plate with exponential decaying temperature and variable mass diffusion in porous medium

“…Additionally, Park and coworkers [14,15] investigated buoyancy-driven flows in a stratified fluid. Rajesh and coworkers [16,17] and Ramakrishna et al [18] explored with different effects over fluid moving via an exponentially accelerated vertical plate. Nouri-Borujerdi et al [19] investigated how the Darcy number affects the onset of convection in a porous medium.…”

“…Figure 1 shows homogeneous and heterogeneous systems which were discussed by Haydon Armstrong and Jason Donev 14 . Impact of chemically reacting along with CF on MHD flow over a nonparallel permeable plate by means of radiation was investigated by Sandhya et al 15 Consequence of chemical reaction and Lorentz force on CF past over a vertical plate by means of Soret was performed by Ramakrishna et al 16 and Nagaraju et al 17 Chemical reacting effect and group theoretical analysis on MHD Casson mixed convection fluid flow by means of the porous medium was explored by Tufail et al 18 Meanwhile, Mathew et al, 19 Balla et al, 20 Balamurugan et al, 21 and Arifuzzaman et al 22 scrutinized the impact of chemical reaction on MHD flow along with Cosinusoidel fluctuating temperature. Muthuraj et al 23 explored the consequence of chemical reactions as well as dust fluid for peristaltic transport among wall properties.…”

“…Bejawada et al [55] have elaborated on the radiation effects on Casson fluid in a porous medium with chemical reaction. Ramakrishana et al [56] conducted a comparative analysis past an exponentially stretching plate to determine the effects of chemical reaction, Soret, and Lorentz forces on Casson fluid. Khan et al [57] treated Casson fluid analytically to study chemical reaction attributes.…”
