Combustion of a fuel jet in a stream of lean gaseous fuel-air mixtures
There are many situations involving the combustion of a fuel jet in an environment that may contain small concentrations of a fuel vapor homogeneously dispersed into the surrounding air. The paper sets out to establish how the presence of such a fuel vapor would influence the burning characteristics of the jet flame and the corresponding flammability limits for both co-flowing and contra-flowing surrounding streams in the presence of the pilot jet diffusion flame. Both laminar and turbulent co-flowing streams were considered that involved a range of gaseous fuel-air mixtures and included methane, hydrogen, propane and ethylene. It is shown that the presence of very small concentrations of a fuel in the surroundings of the jet flame tended to increase the flame thickness and its height and enhanced its stabilization considerably. 8 refs.
