Thermal radiation effect on the Maxwell graphene based nanofluid passing through a squeezing channel

Abstract

This article presents a comparative analysis of flow and heat transfer characteristics of magnetohydrodynamic flow of non-Newtonian base fluid (ethylene glycol) and nanofluid (ethylene glycol + graphene) between two parallel plates moving toward/apart to each other. The study also includes the effects of Joule dissipation, thermal radiation, and heat absorption. The mathematical model that governs the flow of the above-described problem is a single-phase flow model for nanofluids that is augmented with the non-Newtonian Maxwell fluid model. Similarity transformation was used to change controlling partial differential equations into coupled nondimensional ordinary differential equations. The numerical solution is obtained by employing the shooting technique along with fourth order Runge–Kutta Fehlberg method. The impact of several physical characteristics on fluid velocity, temperature, the coefficient of skin friction, and the heat transfer rate is also explored. As a result, this research has the potential to be used in biomedical engineering as well as powder technology.
