Further study has been conducted on the flame structures in a gas-solid two-phase system with inert particle suspensions, in which the suspended particles have two major effects. One is the suppression of combustion by the heat capacity of partilles and the other is the combustion augmentation by the energy recirculation based on radiative heat transfer. This study aimed to clarify the effects of radiative heat transfer on the flam structure and burning velocity in a gas solid two-phase system. In the previous paper, the authors developed a one-dimensional model of a flame in a combustible gas mixture with inert particle suspensions using a strict treatment of radiation, and showed that the effect of augmentation is superior to that of suppression when the loading ratio is small and inferior when it becomes large. Based on this model, the effects of the particle diameter and the radiative properties of the particle, such as scattering albedo, have been clarified quantitatively in this paper.
