Abstract: The authors prepared a series of carbon nanotube (CNT) nanorefrigerants with varying size and amount of nanotubes to determine how these properties affect thermal conductivity. A TPS Instrument was used to measure thermal conductivity of the nanorefrigerants; R113 was used as a host nanorefrigerant. It was determined that higher concentrations of smaller diameter CNTs results in higher nanofrigerant thermal conductivity. A few theoretical models were also used to compare to the experimental results, namely the Hamilton-Crosser, Yu-Choi, and Xue models. A modified Yu-Choi model gave the best agreement with the experimental results.
