Two series of nanofluids were prepared by the researchers, using water as the carrier fluid, and Al2O3 and TiO2 as the nanoparticles; up to 6% particle volume fraction was used. The thermal conductivity and thermal diffusivity of the nanofluids were measured using the transient plane source (TPS) technique, and dynamic viscosity was also measured. The amount of nanoparticle volume fraction affected the value of thermal conductivity, but the nanoparticle cluster ...
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 ...
Describes how second-order terms are important to the hot-strip method, and should be included in situations where a high-current pulse is being used. The authors determined approximate values for the coefficients of second-order terms....
