Parametric study of radiative heat transfer in participating gas–solid flows

Generally, before building a radiative model for a particular gas–solid flow, one has to determine whether the influence of particle scattering and gas radiation are significant. This paper gives the results of parametric studies on the influence of scattering and gas radiation for various gas–solid slabs at high temperature. A statistical Monte-Carlo method has been used in order to solve the radiative transfers into an emitting, absorbing and anisotropically scattering one-dimensional medium. These slabs are constituted of H2O and CO2 gases with a monodispersion of spherical particles. In a first step, Planck means of particle radiative properties of absorption and scattering have been studied at high temperature versus the diameter (10−7
