Thermal Analysis of γAl2O3/H2O and γAl2O3/C2H6O2 Elastico-Viscous Nanofluid Flow Driven by Peristaltic Wave Propagation with Electroosmotic and Magnetohydrodynamic Effects: Applications in Nanotechnological Energy Systems

Abstract

Motivated by new developments in electromagnetic nano/microfluidic energy systems, in this chapter a novel study is described of the thermal performance in unsteady peristaltic electroosmotic hydromagnetic viscoelastic (Jeffreys model) flow of water based-γAl2O3 nanofluids and ethylene glycol-based γAl2O3 nanofluids in a microchannel. The flow is governed by single wave propagation of the microchannel walls which is further controlled by the electroosmosis mechanism with electrical double layer effects. Magnetic field effect and Joule electrical dissipation are also considered in the flow analysis. The two-dimensional governing equations are transformed into non-dimensional form and further simplified using small Reynolds number (Re) and long wavelength (δ ≪ 1) assumptions. The Poisson–Boltzmann equation is deployed to describe the ionic distribution via Debye–Huckel linearization. The variations in axial pressure gradient, axial velocity and temperature distribution for different electrical, magnetic and nanoscale flow parameters are computed and visualized graphically. The findings of the present computations in the optimization of many emerging applications in energy systems nanotechnology including micro/nano-pumping devices, electromagnetic nano-energy harvesting, thermal control of biomimetic microfluidics, nanomedicine, etc.
