A Strategy for Modeling Soot Formation and Radiative Transfer in Turbulent Flames

A strategy has been developed in order to compute unsteady convective and radiative heat transfers in an industrial combustion device. This paper presents the first validation step, which consists in modeling detailed combustion chemistry, soot formation and radiative transfer in a one-dimensional premixed laminar flame with industrial codes. A tabulation method was used to describe gas-phase chemistry; a semi-empirical acetylene-based two-equation model was adapted to predict soot formation and oxidation; and a Monte Carlo method was applied to evaluate radiative transfer in the flame. Applied on three different sets of conditions, the soot model gave results in the experimental uncertainty range of measurements. Radiation calculation showed that soot particles dominate radiative transfer.
