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 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 ...
Al2O3 nanofluids were prepared with 2, 3, and 4 vol% Al2O3 nanoparticles in water for use as a coolant in plate heat exchangers. Using the transient plane source (TPS) technique, the thermophysical properties of the nanofluids were studied. Correlation equations were obtained for Nusselt number and the friction factor for the nanofluids and water. Less nanofluid is required to produce the same amount of cooling than water....
