摘要
为了探讨脉动燃烧器的原理,本文实验研究了Rijke管中热源位置、温度和出口条件等参数对发声频谱、声压的影响,以及Rijke管瞬态发声特性和热源饱和现象。借助Rayleigh准则,作了定性的理论分析,并与实验结果比较。从实验和理论两方面进行新的探索,来研究与Rijke管相关的物理现象。
In order to investigate the Principle on Rijke tube pulse combustor, the influence of the heat source location, temperature, outlet condition on the sound frequency, sound pressure, the instan- taneous characters and heat source saturation are experimentally studied. Theoretical analysis based upon Rayleigh criterion is compared with the experiment results to discuss the phenomena on Rijke tube.
