The Potential Impact of Nanofluid Enhancements on the Performance of Heat Exchangers
TL;DR: In this paper, the potential benefit of using nanofluids in heat-exchanger applications was explored using an ϵ-NTU analysis, and the authors found that the enhancement in number of transfer units (NTU) is largest when the convection resistance associated with the flow to be enhanced is a large contributor to the overall thermal resistance of the baseline heat exchanger.

Anomalously increased effective thermal conductivities of ethylene glycol-based nanofluids containing copper nanoparticles
TL;DR: In this paper, it was shown that a "nanofluid" consisting of copper nanometer-sized particles dispersed in ethylene glycol has a much higher effective thermal conductivity than either pure or pure glycol or even polyethylene glycol containing the same volume fraction of dispersed oxide nanoparticles.
