Tuning the spectral emittance of alpha-SiC open-cell foams up to 1300 K with their macro porosity

Résumé

A simple and robust analytical model is used to finely predict the spectral emittance under air up to 1300 K of alpha-SiC open-cell foams constituted of optically thick struts. The model integrates both the chemical composition and the macro-porosity and is valid only if foams have volumes higher than their Representative Elementary Volumes required for determining their emittance. Infrared emission spectroscopy carried out on a doped silicon carbide single crystal associated to homemade numerical tools based on 3D meshed images (Monte Carlo Ray Tracing code, foam generator) make possible to understand the exact role of the cell network in emittance. Finally, one can tune the spectral emittance of alpha-SiC foams up to 1300 K by simply changing their porosity. (C) 2016 Author(s).
