摘要
Abstract
To study radiative transfer in a participating medium composed of gas and particles, with arbitrary concentrations of particles, a Monte Carlo simulation has been developed. After validation by comparing with other methods,effects of multiple scattering on radiative transfer are investigated. A critical volume fraction fvc is defined to distinguish two radiative flux behaviors versus particles volume fractions : a single scattering zone and a multiple scattering zone. The emissive flux of the slab rises steeply and is dominated by gas and particle single scattering in the single scattering zone, while it approaches a constant value and is dominated by absorption and multiple scattering of particles in the multiple scattering zone.关键词
