An accurate efficient and flexible SNBCK-based unified band model for calculations of spectrally resolved and integrated quantities in participating media containing real-gases
要約
An accurate, efficient and flexible non-grey gas band model was developed based on the statistical narrow-band
model and the correlated-k methodology. Unlike the conventional band models, the new band model
provides gas absorption coefficients and can be coupled with any absorption coefficient based solution technique.
This band model also offers great flexibility and can be easily tailored to suit different applications such as
spectrally resolved quantities or spectrally integrated quantities and different levels of compromise between cpu
time and accuracy without reformulation of the model or regeneration of the model parameters. The model can
also easily be extended to account for particulate scattering and non-grey surface properties. The accuracy and
efficiency of the band model were demonstrated in several examples. The Elsasser narrow-band/Edwards wide-band
model was also evaluated against the unified band model.
