| Abstract | A novel method for implementing the statistical narrowband model into the radiative transfer equation was devised to perform nongrey radiative transfer calculations in three-dimensional absorbing, emitting, and scattering media. In this new method the radiation intensity is split into two parts: the nonscattered part and the scattered part. The nonscattered part is solved accurately using the statistical narrowband model and a ray-tracing technique and does not require iteration. The scattered part is solved with approximation by using the gray-band model to estimate the band correlation between the scattered intensity and the gas absorption coefficient. The accuracy of this method for narrowband radiation intensity prediction was evaluated in a homogeneous H₂O-N₂-Al₂O₃ mixture under both isothermal and nonisothermal conditions by comparing its results with those of the statistical narrowband correlated-K method. This new implementation method alleviates to some extent the difficulty of the band model-scattering incompatibility and offers good results provided the particle loading is not too high. |
