Investigators from Hanbat National University Have Reported New Data on Nanofluids

March 7, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Nanofluids. According to news reporting from Taejon, South Korea, by NewsRx journalists, research stated, "The viscosity and thermal conductivity of ZnO nanofluids with nanoparticle shapes of nearly rectangular and of sphere, were experimentally investigated under various volume concentrations of the nanoparticles, ranging from 0.05 to 5.0 vol.%. The viscosity of the nanofluids increased with increases in the volume concentration by up to 69%."

The news correspondents obtained a quote from the research from Hanbat National University, "In addition, the enhancement of the viscosity of the nearly rectangular shape nanoparticles was found to be greater by 7.7%, than that of the spherical nanoparticles. The thermal conductivity of the ZnO nanofluids increased by up to 12% and 18% at 5.0 vol.% for the spherical and the nearly rectangular shape nanoparticles, respectively, compared to that of the base fluid (water)."

According to the news reporters, the research concluded: "The shape of the particles is found to have a significant effect on the viscosity and thermal conductivity enhancements."
