A Monte Carlo technique follows radiation intensity rays through a dispersion of particles. Rays reflect from and are absorbed by the surfaces of the particles that they encounter. Transmitted radiative fluxes are compared with Monte Carlo simulations of a radiative continuum, using properties from both independent and correlated scattering theories. Whereas both discontinuous (surface) and continuous representations of the medium yield similar results for high porosities (low volume fractions), the continuous representation yields transmission overpredictions for porosities less than 0.9, using independent scattering properties, and for porosities less than 0.7, using correlated scattering properties. The overprediction is less severe for less reflective particle surfaces.
