Abstract

Improved Grouping strategies for spectral subintervals of multi-scale multi-group full-spectrum k-distribution models have been done by considering the influences of both temperature and participating species mole ratio variations on correlated-k characteristics of the spectra of gas mixtures. Finally, evaluations are presented on the calculation of thermal images of supersonic hot jets exhausted from a Chevron ejecting nozzle under a 3-5-micron wave band.
