EXPONENTIAL WIDE BAND PARAMETERS FOR THE PURE ROTATIONAL BAND OF WATER-VAPOR

New exponential wide band parameters are provided for the pure rotational band of water vapor. These wide band correlations are in good agreement with available spectral and total emissivity data. Calculated overlap correction factors for CO2-H2O mixtures based on these new parameters are in good agreement with Hottel's overlap corrections at 400 K and with the calculations of Penner and Varanasi at 811 K. On the other hand, comparisons with Hottel's overlap corrections at 811 and 1200 K show maximum discrepancies of 57 and 46%, respectively. Recognizing the preliminary nature of Hottel's overlap corrections, this discrepancy would probably be best resolved by new experimental data. © 1979.
