Soot and radiation modeling in laminar ethylene flames with tabulated detailed chemistry

Abstract

A strategy has been developed in order to compute unsteady convective and radiative heat transfers in an industrial combustion device. This strategy involves a tabulation method to describe gas-phase chemistry, coupled with a semi-empirical soot model. A Monte Carlo method is used to evaluate gas and soot radiative transfer. This paper presents the first validation step of this strategy, in which four laminar premixed ethylene flames have been simulated. The tabulation method well predicts gas-phase species concentrations, including acetylene, considered as the main soot precursor. The soot model gives results in the experimental uncertainty range of measurements, whereas radiative powers highlight the dominating role of soot particles.
