“…To study the MHD flow of nanofluids in a microchannel, Sarkar and Ganguly 7 created closed-form analytical equations for Nusselt number and temperature distributions together with velocity. The effect of pressure gradient, transverse magnetic field, and electroosmosis of two immiscible metallic of different viscosities was carried out by Gajbhiye et al 8 Jayavel et al 9 provided a numerical analysis for a two-dimensional (2D) Casson hybrid nanofluid motion due to an exponentially extending sheet subject to an electromagnetic field. The effect of heat radiation, magnetic field, and viscous dissipation was analyzed by employing magnetite particles and silver to achieve high temperatures on solar-powered ships by Oreyeni et al 10 Using the power-law model, Moghaddam 11 performed a numerical study of the MHD micropumps.…”

This work investigates the effect of Joule heating and viscous dissipation due to electric double layer (EDL) and electroosmotic effect on steady fully developed electromagnetohydrodynamic flow in a porous microchannel. Dimensionless formulations of the Poisson–Boltzmann, momentum, and energy equations are derived for the electric potential, velocity profile, and temperature distribution in the microchannel. Exact solutions for the temperature distributions and velocity profiles were obtained using the method of undetermined coefficients. The Debye–Hückel linearization is used to get an exact solution for the electric potential. The results showed that the Brinkmann number , Joule heating parameter , Debye–Hückel parameter , Hartmann number , electric field , and suction/injection parameter have a substantial impact on flow formation and heat transfer. Using MATLAB software, graphical simulations are provided to deliver a greater understanding of the influence of relevant parameters on the results achieved.

This paper investigates how gravity modulation affects salt‐finger convection in a micropolar liquid layer confined between two parallel, infinitely long plates separated by a thin gap. The system is heated and has solute added from above. The study uses linear stability analysis to examine when and how salt‐finger convection, driven by the salt‐finger process, begins. To analyze this, the partial differential equations governing the system are solved numerically using normal mode analysis. The Venezian approach is applied to find the critical Rayleigh number and the solutal Rayleigh number, which are key to understanding the onset of convection. Also, the paper explores how different micropolar fluid parameters—such as the coupling parameter, micropolar heat conduction parameter, couple stress parameter, and inertia parameter—affect the system when gravity modulation is present. It is found that gravity modulation can either stabilize or destabilize convection, depending on its frequency. At very high frequencies (approaching infinity), the effect of gravity modulation becomes minimal, having little impact on the convection process. The paper also examines the relationship between the critical Rayleigh number and the solutal Rayleigh number, which are related to heat and solute concentration, respectively.
