Advances in Modeling Radiative Transport in High Temperature Gases

摘要: Thermal radiation heat transfer figures prominently in combustion systems. In perhaps all of these applications the impact transport on environment is clear. Depletion non-renewable energy resources a concern. Industrial utilization under increasing pressure to reduce exhaust pollutant emissions. The generation pollutants flame clearly dependent temperature history related chemical species. Therefore, treatment becomes critical not only accurate determination fluxes load, but also prediction local temperatures with attendant formation. Treatment radiative from gas phase system particularly challenging due strong spectral variation properties (absorption coefficient, K η. absorption spectra gases consist many thousands lines because emit and absorb electromagnetic at discrete frequencies where corresponding photon energies match quantum changes molecules.
