Effective properties of semitransparent radiative cooling materials with spectrally variable properties

چکیده
Radiative cooling is a promising solid-state, non-vapor-compression technology for passive refrigeration and air conditioning. Although this phenomenon occurs naturally, achieving significant amount of to make it technically economically viable requires highly engineered, spectrally selective radiative surfaces. These characteristics difficult estimate, particularly when integrated with other systems such as photovoltaic panels or building envelopes. The complexity further increases the substrate also participates in (along coating). Energy estimation becoming increasingly critical because recent focus on semitransparent coatings that transmit variety colors enhance aesthetic appeal system. Here, we propose an iterative method calculate effective properties, which provides same net would be observed using spectral properties at both coating Compared traditional methods rely either computationally expensive full analysis averaging each surface parameter locally, our proposed focuses calculating provide effect by accounting emissivity, absorptivity, transmissivity collectively, thereby providing overall error less than 0.2%. We believe study will beneficial engineering communities employ complex simulation codes require lumped solar thermal radiation related parameters.

Cooling a hot obstacle in a rectangular enclosure by using a MHD nanofluid with variable properties
In this study, cooling of a hot obstacle in a rectangular cavity filled with water-CuO nanolfuid has been examined numerically. This cavity has an inlet and outlet and the cold nanofuid comes from the left side of the cavity and after cooling the hot obstacle, it goes out from the opposite site. All of the walls are insulated, and the SIMPLER algorithm has been employed for solving the governin...

Various aspects related to the quantum efficiency of the reflective and semitransparent CsI photocathodes have been investigated experimentally . The investigation explored the dependence of the quantum efficiency on the following: the thickness of the photocathode film, the gas used in the parallel-plate avalanche chamber, exposure to water vapor, and the density of the CsI film . With reflect...
