Abstract
This study proposes a new method for fitting coefficients. Traditionally, the WSGG models account only for the temperature on its weighting coefficients; however, the spectral behavior of combustion gases have a strong dependance on other parameters such as the partial pressure. It is proposed a method to account for the partial pressure of a mixture of CO2 and H2O at two fixed mole ratios. The chosen mole ratios are those present on methane and ethanol flames, which are of wide application. The partial results are showing an increasing on the accuracy of the method.
