“…Ahmed et al 27 and Ahmed 28 investigated the consequences of heat sink and chemical reaction on MHD flow. In the context of chemical reaction and thermal radiation, Reddy et al 29 looked into the influence of buoyancy and MHD force upon convective heat and mass transport flow across a movable upright permeable plate. Komaravolu et al 30 studied the influence of viscous dissipation and spanwise cosinusoidally fluctuating temperature on MHD‐free convective boundary layer flow with radiation absorption and chemical reaction.…”

An analytical study of heat and mass transport in magnetohydrodynamic convective flow over an indefinitely long porous plate, which is vertically immersed in the porous medium, is investigated when heat sink, diffusion‐thermo, and thermal radiation are present. A magnetic field with uniform strength has been applied transversely directed into the fluid region. Analysis of diffusion‐thermo impact within the flow problem with constant heat and constant mass flux in the presence of thermal radiation and heat sink is the novelty of the current work. By using the Eckert number E as the perturbation parameter, the regular perturbation approach is used to solve nondimensional governing equations. On the flow and transport characteristics, the effects of Prandtl number, Grashof number, Eckert number, Dufour number, Schmidt number, radiation, magnetic field, and heat sink parameter have been investigated graphically and in tabular form, respectively. The innovative aspect of the current study is the inclusion of the Dufour effect, in addition to constant heat and mass flux at the plate. The Dufour effect can be utilized to improve separation processes, such as distillation, extraction, and chromatography. When the Dufour number and radiation parameter increase, the fluid velocity increases, and while the heat sink parameter increases, it decreases. As dissipation increases, the velocity of the fluid also increases. The concentration of the fluid is enhanced as mass diffusivity increases. When the heat absorption sink grows, the temperature of the fluid decreases.

“…Naramgari and Sulochana [2] analyzed the chemical reaction and thermal radiation effects on a two-dimensional MHD steady flow toward a stretchable sheet using injection/suction. By using a chemical reaction, Reddy et al [3] analyzed the impacts of MHD and buoyancy forces through rotating vertically porous plates. Mishra and Jena [4] explored steady twodimensional incompressible, laminar, and electrically conducted fluids toward a stretchable sheet using magnetic fields and the viscous dissipation effect.…”

Theoretical influence of the buoyancy and thermal radiation effects on the MHD (magnetohydrodynamics) flow across a stretchable porous sheet were analyzed in the present study. The Darcy–Forchheimer model and laminar flow were considered for the flow problem that was investigated. The flow was taken to incorporate a temperature-dependent heat source or sink. The study also incorporated the influences of Brownian motion and thermophoresis. The general form of the buoyancy term in the momentum equation for a free convection boundary layer is derived in this study. A favorable comparison with earlier published studies was achieved. Graphs were used to investigate and explain how different physical parameters affect the velocity, the temperature, and the concentration field. Additionally, tables are included in order to discuss the outcomes of the Sherwood number, the Nusselt number, and skin friction. The fundamental governing partial differential equations (PDEs), which are used in the modeling and analysis of the MHD flow problem, were transformed into a collection of ordinary differential equations (ODEs) by utilizing the similarity transformation. A semi-analytical approach homotopy analysis method (HAM) was applied for approximating the solutions of the modeled equations. The model finds several important applications, such as steel rolling, nuclear explosions, cooling of transmission lines, heating of the room by the use of a radiator, cooling the reactor core in nuclear power plants, design of fins, solar power technology, combustion chambers, astrophysical flow, electric transformers, and rectifiers. Among the various outcomes of the study, it was discovered that skin friction surges for 0.3 ≤F1≤ 0.6, 0.1 ≤k1≤ 0.4 and 0.3 ≤M≤ 1.0, snf declines for 1.0 ≤Gr≤ 4.0. Moreover, the Nusselt number augments for 0.5 ≤R≤ 1.5, 0.2 ≤Nt≤ 0.8 and 0.3 ≤Nb≤ 0.9, and declines for 2.5 ≤Pr≤ 5.5. The Sherwood number increases for 0.2 ≤Nt≤ 0.8 and 0.3 ≤Sc≤ 0.9, and decreases for 0.1 ≤Nb≤ 0.7.

In this analysis, the effect of Catteneo–Christov model on heat alongside mass transport magnetohydrodynamics of a Casson nanoliquid with thermal radiation and Soret–Dufour mechanism is considered. The fluid flow is considered through porous media as the thermophysical attributes such as viscosity along with thermal conductivity are considered to be constant. Suitable similarity transformations were employed on the governing coupled flow equation to yield total differential equations (ODE). An accurate and newly developed spectral method called spectral homotopy analysis method (SHAM) was employed to provide solution to the simplified equations. The numerical method of homotopy analysis method (HAM) is SHAM. SHAM portrays the division of nonlinear equations into linear as well as nonlinear parts. The findings in this study show that an increment in the Casson parameter is seen to elevate the velocity plot at the wall and lessen the velocity far away from the plate. An increase in the Brownian motion and thermophoresis term is observed to speed up the local skin friction coefficient.
