等离激元Ag纳米流体光热转换特性
Investigating on photothermal conversion properties of plasmonic Ag nanofluids
摘要
Abstract
A calculation model incorporating the heat loss is used to study the photothermal conversion characteristics of Ag nanofluids in this work.Adding nanoparticles to the traditional working fluid enhances the light absorption and scattering to obtain better photothermal conversion abilities.The Ag nanofluid with a particle volume fraction of 2.5 × 10-6 leads to the maximum temperature rise of 67.31 ℃,which is 1.8 times that of the base fluid.However,its photothermal conversion efficiency is 2.9 times that of the base liquid since the heat loss is taken into account in the calculation model.With the increase in particle concentration,the temperature rise and the photothermal conversion efficiency gradually increase,and the change rates of temperature rise and photothermal conversion efficiency become gradually small.关键词
