Analysis of Joule heating and Hall effects on the electro-osmotic flow of third-grade nanofluid regulated by peristaltic waves through a porous medium with double diffusion

Abstract

The current analysis is based on the third-grade nanofluid flow triggered by the combined effects of peristaltic pumping and an external electric field. The effects of double diffusion convection and viscous dissipation in nanofluids across a porous symmetric channel were explored. Thermal radiation, the Hall effect and Joule heating are the key phenomena discussed in the flow problem. The governing model is modified by using the Lubrication theory and Debye-Hückel linearization. A highly non-linear system of equations was solved by Mathematica software to scrutinize the effects of Joule heating, Hall effect, electro-osmotic velocity, Grashof numbers, thermophoresis, and Brownian motion on the flow characteristics. Brinkman number and the thermal radiation show opposite characteristics on the temperature profile.
