TL;DR

Nanofluids, solid/liquid suspensions with higher thermal conductivity and viscosity than conventional fluids, are promising for heat‑transfer enhancement, and many studies have examined their effects and flow‑passage modifications. This study aims to investigate natural, forced, and mixed convection heat‑transfer characteristics of nanofluids in single‑ and two‑phase mixture models. The authors review convection heat transfer of nanofluids in closed conduits through numerical simulations and experimental studies. The review confirms that convection heat transfer of nanofluids in closed conduits has been extensively examined both numerically and experimentally.

Abstract

Application of nanofluids in heat transfer enhancement is prospective. They are solid/liquid suspensions of higher thermal conductivity and viscosity compared to common working fluids. A number of studies have been performed on the effect of nanofluids in heat transfer to determine the enhancement of properties in addition to rearrangement of flow passage configurations. The principal objective of this study is to elaborate this research based on natural, forced, and the mixed heat transfer characteristics of nanofluids exclusively via convection for single- and two-phase mixture models. In this study, the convection heat transfer to nanofluids has been reviewed in various closed conduits both numerically and experimentally.
