Resumé

Radiation is the principal mode of heat transfer in utility boiler furnaces. Models for radiative properties play a vital role in reliable simulations of utility boilers and simulation-based design and optimization. The weighted sum of gray gases model (WSGGM) is one of the most widely used models in computational fluid dynamics (CFD) simulation of air-fuel combustion processes. The WSGGM coefficients evaluated by Smith et al. (1982) for several partial pressures of CO2 and H2O vapor are often used for gas temperatures up to 2400K, which is supplemented by the coefficient values presented by Coppalle and Vervisch (1983) for higher temperatures until 3000K. This paper refines the WSGGM in terms of accuracy, completeness and implementation, and demonstrates the use and impacts of the refined model in CFD simulation of a conventional air-fuel utility boiler.

    N2 - Radiation is the principal mode of heat transfer in utility boiler furnaces. Models for radiative properties play a vital role in reliable simulations of utility boilers and simulation-based design and optimization. The weighted sum of gray gases model (WSGGM) is one of the most widely used models in computational fluid dynamics (CFD) simulation of air-fuel combustion processes. The WSGGM coefficients evaluated by Smith et al. (1982) for several partial pressures of CO2 and H2O vapor are often used for gas temperatures up to 2400K, which is supplemented by the coefficient values presented by Coppalle and Vervisch (1983) for higher temperatures until 3000K. This paper refines the WSGGM in terms of accuracy, completeness and implementation, and demonstrates the use and impacts of the refined model in CFD simulation of a conventional air-fuel utility boiler.
