Medium resolution transmission measurements of at high temperature—an update

Calculations of gas thermal radiation transfer in one-dimensional planar enclosure using LBL and SNB models

“…These can be attributed to the missing of hot lines in the HITRAN databases. Bharadwaj and Modest [53] compared the medium resolution transmissivities of CO 2 predicted by CDSD and HITEMP1995 with their experimental measurements and showed that results of the CDSD database were in better agreement with the measured data than those from HITEMP1995. Traditionally, the CDSD database for CO 2 had been more accurate than the HITRAN and HITEMP database prior to the availability of HITEMP2010.…”

An inverse radiation model for optical determination of temperature and species concentration: Development and validation

“…Table 1 Comparison of inverse calculation results using Fateev and Clausen's transmissivity spectra [14] at fine and medium-to-coarse resolutions for CO 2 at 1000 K and concentration at 0.1. Table 2 Inverse calculation results using Bharadwaj and Modest's transmissivity spectra [12,13] for CO 2 at 600 K.…”

“…In the updated HITEMP 2010 CO 2 parameters were calculated from CDSD-1000 [11]. The database was extensively tested against measured medium-resolution spectra of CO 2 [12,13] for the 15, 4.3, 2.7, and 2:0 μm bands at temperatures of 300, 600, 1000, 1300, and 1550 K and measured high-resolution spectra of CO 2 in the 15, 4.3 and 2:7 μm bands at temperatures up to 1773 K [14]. The database was also tested against measured medium-resolution spectra of H 2 O [15] for the 6.3, 2.7 and 1:8 μm bands at temperatures of 600, 1000, and 1550 K and measured high-resolution spectra of H 2 O in the 2.7 and 1:8 μm bands at temperatures up to 1673 K [16].…”

“…Therefore, only the Levenberg-Marquardt method was employed in the scheme described below. The inverse model was validated by retrieving temperatures and concentrations from experimental medium-resolution CO 2 and H 2 O transmissivity data obtained previously [12][13][14][15][16] [12,13,15] for more details on the experiment. High-resolution transmissivity measurements have been made by Fateev and Clausen with an atmosphericpressure high-temperature flow gas cell (HGC), Fig.…”

“…In this study, the CO 2 and H 2 O transmissivity data measured by Bharadwaj and Modest [12,13,15] with mediumresolution (Δη ¼ 4 cm…”
