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 electro-osmotic 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 assumptions. The Poisson-Boltzmann equation is
deployed to describe the ionic distribution via Debye-Hückel 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.
