Thermo‐electrokinetic rotating non‐Newtonian hybrid nanofluid flow from an accelerating vertical surface

This paper explores the combined effects of Coriolis force and electric on rotating boundary layer flow heat transfer in a viscoplastic hybrid nanofluid from vertical exponentially accelerated plate. The comprises two different types metallic nanoparticles, namely silver (Ag) magnesium oxide (MgO) suspended an aqueous base fluid. Casson model is deployed for non-Newtonian effects. An empirical implemented to determine thermal conductivity nanofluid. Rosseland's radiative diffusion flux also utilized. axial electrical field considered Poisson–Boltzmann equation linearized via Debye–Hückel approach. resulting coupled differential equations subject prescribed conditions are solved with Laplace transforms. Numerical evaluation solutions achieved MATLAB symbolic software. A parametric study impact key parameters velocity, transverse nanoparticle temperature Nusselt number conducted both (Ag–MgO)–water unitary (Ag)–water With increasing volume fraction there reduction velocity temperatures, whereas distinct elevation nanofluids. Elevation absorption parameter strongly decreases it enhances velocity. Increasing radiation boosts temperatures. significantly accelerates flow. Negative values Helmholtz–Smoluchowski decelerate positive accelerate it; opposite behavior observed Taylor damps (primary) transversal (secondary) Grashof but achieves higher numbers than these decreased greater effect (due transport away plate surface), Prandtl absorption. reduced time progression consistently compared computations provide insight into more complex electrokinetic rheological nanoscale flows relevance biomedical rotary electro-osmotic separation devices.
