A simple method is presented for predicting the thermal radiation from nonisothermal combustion systems containing variable concentrations of water vapor, carbon dioxide, and soot. Less complex than narrow and even wide-band models, the simplified technique has been shown to agree quantitatively with results of a complex narrow-band model. For combustion conditions found in typical fires and furnaces (20 to 200 cm pathlengths, temperatures between 800 and 1800 K), calculations can be performed within about 8% of those made by the complex model, and with savings of two orders-of-magnitude in computation time. |
