“…A computational analysis of the Hall current and thermal radiation effects of MHD free convective mass and energy transfer radiating fluid flow in the soret effect and heat generation was reported by Sivaiah and Reddy (2017). Ojemeri and Hamza (2022) put forth a theoretical investigation of MHD natural convection heat generating/absorbing fluid flow controlled by Arrhenius kinetic in a microchannel. Thermal radiation plays a significant role in convective heat transfer processes which consist of high temperatures for example, gas turbines, solar power technology, and nuclear power plant.…”

This article investigates the MHD free convection flow of a Casson fluid that is electrically conductive, affected by thermal radiation effect in a vertical porous channel. The resulting solutions of the leading differential equations describing the velocity and temperature flows characteristics are obtained analytically using regular perturbation method. The actions of Casson fluid parameter, magnetic field effect, thermal radiation parameters on the velocity field, temperature distribution, skin friction coefficient and rate of heat transfer has been presented for relevant temperature jump and velocity slip conditions. The results obtained revealed that by taking varying values of the major controlling parameters, such as Casson parameter, thermal radiation parameter, magnetic field effect, rarefaction parameter and wall ambient temperature difference ratio parameter, the velocity and temperature profiles are substantially influenced. Additionally, when the Casson parameter is set to be 1000, the numerical computations of these findings agree very well with those of Abbas et al., 2020.

“…In light of the foregoing, Hamza et al (2023) recently investigated a theoretical study on the impact of Arrhenius-controlled heat transfer flow influenced by an induced magnetic field in a microchannel. Ojemeri and Hamza (2022) proposed an analysis of Arrhenius kinetically provoked heat source/sink fluid in a microchannel using the homotopy perturbation technique. Jha and Malgwi (2019a) outlined the implications of Hall current and ion-slip on hydro-magnetic heat transfer flow in a vertical micro-channel affected by an applied magnetic field.…”

The theoretical analysis of steady mixed convection with Arrhenius-controlled heat flow for a viscous and an electrically-conducting fluid traveling across an isothermally heated vertical parallel plate in a slit micro-channel is investigated in this study. One wall had super-hydrophobic slip and a temperature spike, while the other did not. A semi-analytical technique (perturbation series) was employed to analyze the nonlinear and coupled leading equations. The results were carefully scrutinized, and the effects of the relevant and pertinent parameters were illustrated using various plots. It is concluded from this work that the actions of mixed convection and chemically reacting factors are noticed to substantially strengthen the fluid movement in the micro-channel for a constant pressure gradient. Additionally, the function of heat source parameter is depicted to raise the fluid flow while heat absorption parameter yields the reverse phenomenon. In the fields of engineering and medicine, it is essential to understand these fluids' characteristics. Owing to the lubrication of micro-channel boundary surfaces where conductivity and viscosity interact with thermos-physical behavior, the results of the present investigation can significantly enhance the functioning of micro-electro-mechanical systems (MEMS) and micro-devices relying on micro-fabrication processes.
