TL;DR: In this paper, a laminar flow forced convection heat transfer of Al2O3/water nanofluid inside a circular tube with constant wall temperature was investigated experimentally.
766 citations
TL;DR: In this article, the authors considered the forced convection flow of water and ethylene glycol inside a uniformly heated tube that is submitted to a constant and uniform heat flux at the wall.

TL;DR: In this paper, an experimental energy storage system has been designed using a horizontal concentric tube heat exchanger incorporating a medium temperature phase change material (PCM) Erythritol, with a melting point of 117.7°C.
456 citations
TL;DR: In this article, a single-and two-phase model with either constant or temperature-dependent properties is employed to develop laminar forced convection flow of a water-Al2O3 nanofluid in a circular tube, submitted to a constant and uniform heat flux at the wall.

TL;DR: In this paper, the authors summarized the important published articles on the enhancement of the convection heat transfer in heat exchangers using nanofluids on two topics: theoretical and experimental results for the effective thermal conductivity, viscosity and the Nusselt number reported by several authors.
Abstract: The purpose of this review summarizes the important published articles on the enhancement of the convection heat transfer in heat exchangers using nanofluids on two topics. The first section focuses on presenting the theoretical and experimental results for the effective thermal conductivity, viscosity and the Nusselt number reported by several authors. The second section concentrates on application of nanofluids in various types of heat exchangers: plate heat exchangers, shell and tube heat exchangers, compact heat exchangers and double pipe heat exchangers.
