Abstract : Electroactive peristaltic transport in non-Newtonian nanofluids is of growing importance in advanced thermal management systems, microfluidic devices, electrochemical reactors, and bioinspired mechanisms for toxicant extraction. Motivated by these applications, the present study aims to examine the coupled thermal and chemical transport characteristics of a chemically reactive electroactive Ree–Eyring nanofluid flowing through an inclined, porous, and asymmetrically deforming microduct under mixed convection conditions. The mathematical model incorporates the combined effects of electroosmosis, magnetic field with Hall current, thermal radiation, internal heat generation, Brownian motion, and thermophoresis. Using the lubrication approximation and Debye–Hückel linearization, the governing nonlinear equations are non-dimensionalized, and analytical solutions are obtained via the homotopy perturbation method. The results reveal that electroosmotic forcing significantly enhances fluid transport near the upper wall, while magnetic and chemical reaction parameters strongly regulate pressure gradients and mass diffusion. Thermal behavior is markedly influenced by heat generation and nanoparticle dynamics, whereas radiative effects suppress temperature levels in the core region. Overall, the study provides new physical insights into electroactive peristaltic transport of chemically reactive non-Newtonian nanofluids, offering a useful theoretical framework for the design of eco-inspired pumping systems and microscale hazardous material management technologies.
