Nanofluid research is focused on two specific areas of testing: synthesizing new nanofluids with enhanced thermal properties, and finding new applications for nanofluids. Nanofluids are conventional heat transfer fluids with suspensions of thermally conductive nanoparticles. In this study, TiO2 (titanium dioxide) nanoparticles are used to enhance the base fluid propylene glycol (PG). The Thermal Constants Analyzer measured the thermal conductivity of the TiO2/PG nanofluid using the transient plane source (...
Nanocomposites of polyaniline nanofibers reinforced in epoxy were prepared and their ultrasonic velocities, ultrasonic attenuations, and thermal conductivities were measured over a temperature range of 298-373 K. It was found that the ultrasonic velocity decreased with increasing temperature, but increased with increasing concentration of polyaniline nanofibers in the epoxy matrix. These two trends were opposite for the ultrasonic attenuation, and the thermal conductivity was found to increase with increasing temperature ...
