摘要: This work focuses on the study of thermal diffusivity and physical properties nanofluids with very low concentrations silver or gold nanoparticles. Thermal measurements were performed by means lens spectroscopy in dual beam configuration. Improvements 20 16 % observed for nanofluids, respectively, comparison pure water. The estimation size distribution metallic nanoparticles was obtained through fitting extinction spectra via Mie theory images field emission gun scanning electron microscopy.
