摘要：

Radiant properties of a two-dimensional layer of diffusely reflecting spherical particles have been evaluated without resorting to any simplification. Approximate expressions have been derived to correlate the results with particle emissivity and layer concentration of particles. The calculated layer properties are used in the multiple-layer model to compare and discuss the capability of both pseudo-homogeneous and heterogeneous models for predicting radiative heat transfer rates in dense particulate media.
