Electroosmotic Effects on Peristaltic Transport of Ree‐Eyring Nanofluid with Double Diffusive Convection in Symmetric Microchannel

This study examines significant applications across various domains, including microfluidics, biomedical engineering, and energy systems, focusing on the advancement of lab‐on‐a‐chip technologies, electrokinetic pumps, and micro‐scale filtration systems. A detailed investigation is conducted to explore the combined influence of peristaltic transport, double‐diffusive convection, electroosmosis, magnetohydrodynamics (MHD), Hall current, viscous dissipation, thermal radiation, and porous medium flow in the presence of a heat source. The Poisson–Boltzmann ionic distribution is approximated using the Debye–Hückel method. The lubrication approach is adopted to make the system simpler. To solve nonlinear partial differential equations in a more sophisticated manner and to improve the reliability of models in various scientific and technical domains, this work uses the homotopy perturbation technique (HPM). A thorough investigation is conducted into the effects of key parameters on the flow characteristics using graphical representations. The results of this investigation show that, in the presence of double‐diffusive convection, the Helmholtz–Smoluchowski velocity parameter can improve the velocity distribution of the Ree‐Eyring nanofluid. Notable variations in trapped boluses are noticed due to the influence of some influential parameters. Furthermore, the present outcomes are validated with previous discoveries under specific conditions.
