Optimization of high temperature SiC volumetric solar absorber
Focusing on radiative properties (absorption and scattering coefficient, scattering phase-function) of silicon carbide foams, several predictive models are compared to spectral transmittance and reflectance measurements (bi-directional and directionalhemispherical) in the aim of determining new correlations based on ceramic foam characteristics (struts/pores size and porosity). A mono-dimension...
متن کاملBrown carbon: a significant atmospheric absorber of solar radiation?
Several recent observational studies have shown organic carbon aerosols to be a significant source of absorption of solar radiation. The absorbing part of organic aerosols is referred to as “brown” carbon (BrC). Using a global chemical transport model and a radiative transfer model, we estimate for the first time the enhanced absorption of solar radiation due to BrC in a global model. The simul...
متن کاملExperimental Investigation on the Effect of Partially Metal Foam inside the Absorber of Parabolic Trough Solar Collector
In the present work the efficiency of a solar parabolic trough has been investigated experimentality. parabolic trough solar collector constitute a proven source of thermal energy for industrial process heat and power genaration. The impact of using the partially porous media in the absorber on the efficiency of PTC (parabolic trough collector) has been investigated. The porosity of copper foa...
متن کاملMetasurface Broadband Solar Absorber
We demonstrate a broadband, polarization independent, wide-angle absorber based on a metallic metasurface architecture, which accomplishes greater than 90% absorptance in the visible and near-infrared range of the solar spectrum, and exhibits low absorptivity (emissivity) at mid- and far-infrared wavelengths. The complex unit cell of the metasurface solar absorber consists of eight pairs of gol...
متن کاملThermodynamic analysis of a novel solar water heating system during low sun radiation in Iran
This paper reports a plenary thermodynamic model of a novel solar system for water heating in buildings. Energy and exergy analyses are used to characterize the exergy destruction rate in any component and calculate system overall efficiency. The system consists of a solar evaporator, a heat exchanger to produce hot water, and an auxiliary pump. A computer simulation program using EES software ...
