Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids. In this study, the thermal conductivity of aqueous alumina and multi-walled carbon nanotube (MWCNT) nanofluids was measured using the transient plane source (TPS) method with a thermal constants analyzer TPS. During each trial, 0.015 W of power were administered to each sample for two seconds. Results of the experiment showed ...
