✦ Synopsis
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 ¼ 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.
