Abstract: In this study, multi-walled carbon nanotubes (MWCNTs) were added to Al2O3/water nanofluids to determine their heat transfer and temperature drop properties compared to water and Al2O3/water nanofluids. A TPS 2500S thermal constants analyzer measured the thermal conductivity of the Al2O3/water nanofluids using the transient plane source (TPS) method. The thermal conductivity of Al2O3/water nanofluids was further enhanced with the addition of MWCNTs because they occupy fluid space and form thermally conductive nanoparticle/CNT networks.
