Abstract
Impingement jet cooling experiment using nanofluid as working fluid is carried out under the forced convective boiling condition. Heat transfer coefficient of silver-water nanofluid of 0.01wt% is higher than that of pure water. However, heat transfer coefficient of alumina-water and silica-water nanofluids of 0.1wt% is lower than that of pure water. The deposition of nano-particles over the heat transfer surfaces is observed for alumina-water and silica-water nanofluids after the experiments, on the other hand it is not observed for silver-water nanofluid. This observation may somewhat relates with the results of heat transfer coefficient stated above.
