EVALUATION OF THE SNB BASED FULL-SPECTRUM CK METHOD FOR THERMAL RADIATION CALCULATIONS IN CO2-H2O MIXTURES
摘要
The statistical narrow-band model based full-spectrum correlated-k method was developed for calculations of thermal radiation in non-isothermal and inhomogeneous CO2-H2O-grey particulate mixtures. Two different methods to handle mixtures of CO2 and H2O were proposed. The accuracy and efficiency of these two implementations of the statistical narrow-band based full-spectrum correlated-k method for calculations of thermal radiation in CO2-H2O-N2 mixtures were evaluated against the standard statistical narrow-band correlated-κ method and the optimized 9-band model in the calculations of two non-isothermal problems in a three-dimensional rectangular enclosure. Results of the first implementation method are slightly more accurate but somewhat less efficient than the optimized 9-band model. The second implementation method is very efficient but is also considerably less accurate.
