“…The temperature and fluid rate in the bottom channel isrising. Momentum and energy fluids improve as the thermostat's strength and quantity of sticky heating source substances grow, resulting in a significant increase in temperature, as reported by Hamza and Abdulsalam [30]. Decreased perceived flow increased fluid velocity, which elevated the temperature.…”

The area of fluid dynamics known as magnetohydrodynamics (MHD) studies how magnetic fields affect fluid flow. Its existence in a variety of geometries has become an enthralling aspect of science and technology. Cooling nuclear reactors and medical research are all practical uses. In the current work, we investigate free convective slip flow between two vertical walls generated by convective heating of the left wall in steady and unsteady state magnetohydrodynamics with chemical kinetic exponents. In general, we present two sets of solutions: a constant state and a transient state. The implicit finite difference method and the homotopy perturbation approach were used to obtain the two solutions. Line graphs were utilized to depict the effects of various flow factors included in the system.The findings demonstrated that a slight rise in MHD decreases the momentum barrier layer by inducing the Lorentz force.However, slows the flow and depictsthe best view at the biomolecular chemical reaction index. Furthermore, it was demonstrated that in contrast to Arrhenius and Sensitized, higher fluid velocity and temperature at biomolecular chemical processes result in significant increases in temperature and velocity gradients, while fluid velocity is found to be significantly improved with a slight increase in a porous medium. Significant agreement can also be seen when comparing the steady state and the unsteady solution.

“…al [36] inspect melting effect on Cattaneo-Christov and thermal radiation features for aligned MHD nanofluid flow comprising microorganisms to leading edge. Recently, Hamza and Abdulsalam [37] reported that the Lorentz force opposing the fluid flow causes fluid velocity to drop as the Hartmann number grows. This results in a decrease in boundary layer thickness, which causes a decline in momentum region.…”

The current study examined the effects of magnetohydrodynamics (MHD) on time-dependent mixed convection flow of an exothermic fluid in a vertical channel. Convective heating and Navier’s slip conditions are considered. The dimensional nonlinear flow equations are transformed into dimensionless form with suitable transformation. For steady-state flow formations, we apply homotopy perturbation approach. However, for the unsteady-state governing equation, we use numerical technique known as the implicit finite difference approach. Flow is influenced by several factors, including the Hartmann number, Newtonian heating, Navier slip parameter, Frank-Kamenetskii parameter, and mixed convection parameter. Shear stress and heat transfer rates were also investigated and reported. The steady-state and unsteady-state solutions are visually expressed in terms of velocity and temperature profiles. Due to the presence of opposing force factors such as the Lorentz force, the research found that the Hartmann number reduces the momentum profile. Fluid temperature and velocity increase as the thermal Biot number and Frank-Kamenetskii parameter increase. There are several scientific and infrastructure capabilities that use this type of flow, such flow including solar communication systems exposed to airflow, electronic devices cooled at room temperature by airflow, nuclear units maintained during unscheduled shutoffs, and cooling systems occurring in low circumstances. The current findings and the literature are very consistent, which recommend the application of the current study.

The consequences of chemically reactive fluids have provoked many researchers due to their potential to enhance the behavior of heat. Hence, this article discussed a theoretical investigation to explore the actions of Arrhenius chemical reaction and Hall current on hydro-magnetic free convection of a viscous fluid flowing along an upstanding micro-channel. Subject to the required boundary conditions, the governing coupled equations representing the flow pattern in non-dimensional form were solved using the homotopy perturbation method (HPM). Line graphs are also used to generate expressions for energy, momentum, volume flow rate, drag force, and Nusselt number in both primary and secondary flow directions as a function of regulating parameters like chemical reaction, Hall current, rarefaction, and wall ambient temperature difference ratio. It is worthy of note that the fluid temperature and the fluid flow are substantially propelled by the viscous heating term in the Arrhenius chemical reaction of the system for growing values of the wall ambient temperature difference ratio parameter. Additionally, it is noticeable that volume flow rate performance is seen as a growing influence of viscous heating and rarefaction parameters. The findings of this study can be applied to a wide range of electrically controlled devices, thermal and petro chemical engineering, and the serviceability of industrial products.
