Abstract: This article studied the thermal conductivity values and measurements for the following two systems using the transient hot wire (THW) and transient plane source (TPS) techniques: ethylene glycol with added CuO, TiO2, or Al2O3 nanoparticles and water with added TiO2 or Al2O3 nanoparticles or multiwall carbon nanotubes (MWCNTs). A TPS technique using Hot Disk instrument (TPS 2500 S Hot Disk thermal conductivity analyzer) was employed to conduct measurements to provide support for the results of the thermal conductivity measurements that were determined using the transient hot wire method. It was found that in all cases the agreement was within 2%. Thus, the Hot Disk thermal constants analyzer measurements were supportive of the transient hot wire ones, despite the difference of scales involved.
