AbstractAccurate calculations of real-gas radiation are inherently difficult due to the extremely strong spectral variations of gas radiative properties. In combustion, real-gas practically means CO2 and H2O present in the combustion products for hydrocarbon fuels. Oversimplified gas radiation models yield large errors in the prediction of gas radiation and cannot be used as a reliable radiation submodel in an overall combustion or flame code. The exact line-by-line (LBL) calculations, however, are far too computationally intensive to be applied to problems of practical interest. Therefore, substantial research efforts have been devoted to development of accurate and efficient nongrey gas radiation models.
