英文摘要: Abstract(#br)The plasmonic effect is introduced in solar thermal area to enhance light absorption. The solar irradiance within the nanofluid attenuates rapidly at wavelength of 560 nm, contributed from the localized surface plasmon resonance (LSPR) excited on the SiO 2 /Au nanoshells. A one-dimensional transient energy equation coupled with radiative transport equation is solved to analyze the photothermal efficiency of SiO 2 /Au nanofluid. The use of plasmonic nanoshell-based nanofluid can significantly reduce the concentration of nanofluid used in direct solar thermal collector. For an equal temperature rise, the volume fraction of SiO 2 /Au nanoshell-based nanofluid is only 1/5 of Au nanofluid. This is a great advantage of employing plasmonic nanoshell-based nanofluid for solar thermal...
