Undamped Oscillatory Condition Analysis of Pulse Combustor

本文通过一个理想化的模型,对脉冲燃烧器进行了质量及能量平衡,从而得出描述脉冲燃烧过程的微分方程及其稳定准则,本文还得出了预测脉冲燃烧器运行频率的表达式,并着重讨论了稳定启动的条件及方法。

Through the conservation of energy and mass on an ideal model of the pulse combustor, the analysis attempts to establish the differential equations, which describe the pulse combustion process, and their stable criteria. The analysis also presents a formula which can predict the frequency of the pulse combustor, and specifically discusses the conditions and methods of stable starting of the pulse combustor.
