Abstrakt

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.
