Absorption and scattering coefficients are calculated for discrete particle sizes using the Dave treatment of Mie scattering. The model incorporates a one dimensional beam approximation and couples the particulate and gaseous heat transfer equations. An existing gaseous infrared radiation computer code has been updated to included particulate scattering,absorption and emission in its calculation of radiant heat transfer from combustion products and exhaust plumes. It is shown that the present model is an improvement over models which merely add independent computations of gaseous and particulate radiation. (Author) 收起
