摘要：

A new implementation to determine the correlated k values as used in full-spectrum correlated k-distribution methods for inhomogeneous media is presented, which conserves radiative emission and significantly improves the accuracy of the full-spectrum correlated k-distribution method in strongly inhomogeneous media. In addition, an update of a previous high-accuracy, compact narrow-band k-distribution database is given. The new narrow-band database utilizes the latest spectroscopy databases to ensure accuracy at elevated temperatures and pressures. Differences between the two versions of narrow-band k-distribution databases as a result of the change of spectroscopy databases are illustrated. (C) 2014 Elsevier Ltd. All rights reserved.
