“…The boundary layer free convective unsteady flow of an incompressible micropolar fluid under a uniform magnetic field is studied by Patel 18 in symmetric and asymmetric boundary conditions with thermal radiation. Kumar et al 19 identified unsteady free convection and mass transmission passing through an infinite vertical absorbent plate with a chemical response using the suction parameter. The dissipation of joules and viscosity on MHD flow passing over a porous plate for a normal fluid was explained by Anjali Devi and Ganga 20 Convection mixed MHD stream with radiation, chemical reaction, and dissipation through a porous material was investigated by Zigata 21 .…”

This article discusses the impact of chemical reaction and radiation on an unstable two‐dimensional laminar flow around a viscous fluid over a semi‐infinite, vertical absorbent surface that moves progressively. The governing classification of partial differentiation was converted into an ordinary differentiation system in this case. To get numerical solutions, the Galerkin finite element technique is applied to nondimensional velocity, micro‐rotation, temperature, and concentration profiles. The consequences of skin friction, the combined pressure quantity, the mass, and heat assignments at the boundary are formed using different fluid properties and flow conditions. Physical quantities and their effects Graphs depict the radiation parameter R, thermal conductivity k, Eckert number Ec, and other velocities, micro‐rotation, temperature, and concentration factors. The main findings of this current problem is showing the chemical reaction effects on velocity and concentration. It is observed that both the velocity and concentration of the fluid decrease when Kr increases.

“…Anjalidevi et al explored (9) the results of a chemical response, mass and heat transference on smooth liquid flow along with a semi-infinite parallel dish. Kumar et al (10) deliberated contemplate the progression of insecure free convection and move of mass going through an endless vertical permeable plate with a synthetic response by considering pull boundary and gooey dissemination if the plate moves in its plane. The theme of nonlinear radiation and blended convection of the MHD warmth and mass exchange of Maxwell nano liquid stream in permeable media with Arrhenius dynamic response is inspected by Salawu et al (11) Salahuddin et al (12) initiated MHD sway on dramatically differing consistency of Williamson liquid stream with variable conductivity and diffusivity.…”

Objective: To study the effects of chemical reaction and heat source parameter on MHD Free Convection Flow Past a Vertical Porous Plate. Method: The problem is represented by coupled non-direct fractional differential conditions. The non-dimensional conditions of the issue have been tackled mathematically utilizing the Finite-Element strategy. Findings: The effects of governing parameters such as chemical reaction, heat source, permeability, radiation and many others are discussed quantitatively with the help of graphs in these flow fields like velocity, temperature, concentration with the help of skin friction, Nusselt number and Sherwood number. Novelty: The accurateness of the solution to the problem was verified by comparing it with the published previously. The compatibility between the results was found to be high. To strengthen the validity of the numerical results were presented in this work.

The aim of the study is to measure the Dufour number effects on the flow patterns and heat transfer in an exponentially accelerated infinite vertical plate embedded in a porous medium in the presence of heat source and chemical reaction. Time‐dependent variations in temperature, velocity, and other factors should be taken into consideration due to the flow's unsteadiness. The fluid considered is a gray, absorbing/emitting radiation but nonscattering medium. Using the finite element method, a set of nondimensionless equations is solved analytically. Results are discussed graphically for concentration, temperature, and velocity profiles. Skin friction, Sherwood number, and Nusselt number are also explained for flow parameters through graphs.
