Abstract
The article describes a model of the mechanisms governing the stability of turbulent diffusion flames. It is based on the nature of the large scale motions that have been observed in turbulent jets and includes a process for maintaining a stable flame. An analysis, based on the proposed model, leads to a single parameter which determines the blowout velocity of pure fuels and fuels diluted with air and CO2. The parameter is the ratio of two times: a characteristic chemical reaction time and a time associated with the mixing of reentrained hot products into fresh reactants. The agreement with a set of experimental observations for both pure and diluted gases is good.
