| 内容記述 | The ignition and flame stabilization of the flowing combustible gaseous mixtures by a hot jet of combustion products or inert gases are important phenomena in many apparatus, such as ramjet burners or rocket combustion chambers. In the present paper, the problem of the ignition of the combustible gaseous stream by a hot jet is formulated and analyzed, considering a simplified model and using the boundary layer approximation of aerothermochemistry. A one-step unopposed global reaction following any order reaction kinetics with temperature dependence according to the Arrhenius rate law is assumed. The Prandtl and Schmidt numbers are assumed to be equal, then a similarity between the equation of energy and the diffusion equation exists, greatly simplifying the analysis. Approximate but general analytic expressions for the N'th approximation to the temperature and concentration profiles are obtained. These analytic results are applied to the problems of the thermal decomposition of azomethane and the thermal decomposition of hydrazine. Numerical calculations are carried out for the first-order approximation. It is confirmed that if the width of the jet is large enough, then the ignition always takes place at some point of the stream, but if the width of the jet is small, whether or not the ignition takes place depends on the width of the jet and the temperature of the hot gas. | |||||||
