Multi-group full-spectrum \(k\)-distribution database for water vapor mixtures in radiative transfer calculations. (English) Zbl 1042.76592

Summary: A thorough investigation of the absorption coefficient dependence on temperature and pressure has been performed for water vapor, and a 32-group database has been assembled for H\(_2\)O mixtures at atmospheric pressure, based on the multi-group full-spectrum correlated \(k\)-distribution model. The method is fully scalable, i.e., spectral groups from the database can be combined to obtain coarser group models (\(N=1,2,4,...\)) for greater numerical efficiency (accompanied by slight loss in accuracy). The databases for CO\(_2\) and H\(_2\)O, together with the random-overlap mixture model, have been used to simulate a practical combustion problem.
