“…39 Variously referred to as electrokinetics or electrohydrodynamics (EHD), this discipline of modern fluid dynamics focuses on the interaction of electrical fields (either static or alternating) and viscous ionic liquids. It features in fertility control in biomechanics, 40 capillary phase change devices in industrial heat transfer, 41 bioinspired micro-pumping systems, 42 electro-chemical surface modification in nontraditional machining, 43 and next generation tunable coatings for naval and biomedical devices. 44 Electrical fields in all these applications have been shown to achieve exceptional effectiveness in controlling microscale (and nanoscale) phenomena, which lead to improved designs.…”

Motivated by emerging applications in bio-microfluidic devices, the present study rigorously examines the generalized Taylor–Gill hydrodynamic dispersion of a point source solute injected into a microchannel, influenced by a constant axial static electric field along the channel and charged surface with different wall potentials. The solute engages in a first-order irreversible chemical reaction at both the microchannel walls. By incorporating different wall potentials and absorptive coefficients at the lower and upper walls, the current transport model for electro-osmotic flows is extended to encompass a wider range of applications. The solute transport phenomenon is intricately modeled using the unsteady convective diffusion equation. Employing Gill's generalized dispersion model, a concentration decomposition technique, up to the third-order accuracy, we meticulously analyze the transport process. Furthermore, a comprehensive comparison between analytical outcomes and numerical simulations using the Brownian Dynamics method is undertaken, enhancing the robustness of the analytical approach. The scattering process is mainly analyzed with the help of exchange, convection, dispersion, and asymmetry coefficients, along with the mean concentration profile. The effect of initial solute release at various vertical locations in the microchannel is shown to exert a considerable impact on all the transport coefficients at initial times.

“…Taking into account the application of the external electric field, the mobile ions in the EDL have a tendency to migrate and generate a fluid body force, which enables a bulk liquid to move through a viscous effect. Numerous experimental, theoretical and numerical studies on the EOF for different kinds of fluids have been published in the literature [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] . Modern technology has increased interest in flow and heat transfer research, which encompass heat exchangers, fluid transport, chemical processing equipment, and micro-electronic cooling.…”

“…parallel plate geometries) have emerged in recent decades including atomizers, 10 corona-based duct flows, 11 electrode gas pump channels, 12 electrostatic precipitators, 13 dielectric barriers for electro-fluid injection, 14 EHD heat exchangers, 15 coolants for circuits, 16 thermal enhancement, 17 and bio-inspired microfluidic pumping systems. 18 As with MHD, some popular electrohydrodynamic dimensionless numbers arise in numerical and theoretical studies of EHD duct flows and these include the electrical Hartmann number and electrical Reynolds number. The many studies communicated on either MHD duct or EHD duct flows have demonstrated that generally transverse magnetic field damps flows whereas axial (longitudinal) electrical field accelerates flows.…”

Motivated by novel developments in smart non-Newtonian thermal duct systems, a theoretical study has been presented in this article for electro-magneto-hydrodynamic (EMHD) buoyancy-driven flow of a fourth-grade viscoelastic fluid in a vertical duct with quadratic convection. The viscosity of the fourth-grade fluid model is assumed to be temperature-dependent, and the Reynolds exponential model is deployed. Viscous heating and Joule dissipation effects are included. The duct comprises a pair of parallel electrically insulated vertical flat plates located a finite distance apart. Via suitable scaling transformations, a nonlinear boundary value problem is derived for the momentum and heat transport. A homotopy perturbation method (HPM) solution is obtained coded in Mathematica symbolic software. There is a considerable enhancement in wall skin friction with an increment in fourth-grade fluid parameter, Brinkman number, electrical field parameter, thermal buoyancy parameter, and quadratic thermal convection parameter. However, skin friction is strongly reduced with a rise in variable viscosity parameter, Hartmann (magnetic) number, and electromagnetic heat generation to conduction ratio. Nusselt number magnitudes are elevated with increase in variable viscosity parameter, thermal buoyancy parameter, and quadratic thermal convection parameter, whereas they are significantly suppressed with increment in fourth-grade fluid parameter, Brinkman number, and Hartmann magnetic number.
