Abstract : Experiments on spontaneous combustion characteristics of hydrogen injected into a supersonic stream of hot air are described in detail. The results are presented and compared with a theory developed for premixed reactants. The experimental data show that if the initial static temperature and the static pressure of the air stream are high enough then diffusion will be rate controlling and a mixing theory using equilibrium chemistry could be used in analyzing the combustion process. If the chemical reactions are slow, the behavior of the combustion process can be studied as a system where mixing and diffusive effects are absent. The ignition delay times inferred from the initiation of the pressure rise along the burner are in good agreement with those predicted by the empirical correlation. The static temperature exerts a greater influence on the ignition delay time than the static pressure. The static pressure level is an important parameter in determining the time for complete combustion. (Author)
