EDL impact on mixed magneto-convection in a vertical channel using ternary hybrid nanofluid

Abstract

Electro-osmotic transportation of conducting ionic nanofluids in vertically bounded arrangements has been expansively researched due to its vast assortment of engineering and medical applications, such as soil study, fluid dialysis, chemical processing, capillary electrophoresis, planar chromatography, separation techniques, and other real interests. On that account, in the manuscript, a theoretical model is constituted to simulate the fully developed mixed convective flow of ionic ternary hybrid nanofluid persuaded by electroosmosis and magnetohydrodynamics in a long vertical non-conducting channel under linearly changing temperature on channel walls. The classical Poisson-Boltzmann equation is employed to extract the electric double layer (EDL) impact on the flow formation via Debye-Hückel linearization conjuncture. The leading partial differential equations delineating the flow are formulated based on the general laws of conservation of momentum and energy. The relevant dimensionless setup transforms the flow model to a simplified equivalent model, which is solved analytically. The new results are comprehensively examined in terms of basic flow, magnetic, and thermal characteristics for various implanted parameters via multiple graphs and tables. Graphical outcomes confessed that the magnetic field and Debye-Hückel parameters have striking impacts on the stream features. Thin EDL supports speeding up the fluid motion through the channel domain. A noteworthy result noted from the examination is that the concentration of tri-hybridized nanoparticles in pure water is an issue that effectively delays the commencement of flow instability in the channel domain under the magnetic setting. The present study’s findings may be valuable for designing electromechanical devices, nanofluidic devices, micropumps, solar energy systems, etc.
