运用ＣＨ离子浓度传感器及其测试系统，研究燃烧室内低压对两态混气紊流燃烧的压力脉动和放热脉动的影响。结果表明，燃烧装置的结构参数决定了燃烧装置的固有频率，随着压力升高，剧烈化学反应区向上游移动，对蒸发式稳定器而言，低压下油气比对压力脉动值影响较小。
The influence of low pressure in the combustion chamber on pressure pulsation and exothermic pulsation of a two-state mixed gas turbulent combustion was investigated by using CH ion concentration sensor and its testing system. The results show that the structural parameters of the combustion device determine the natural frequency of the combustion device. As the pressure increases, the violent chemical reaction zone moves upstream. For the evaporative stabilizer, the ratio of oil to gas at low pressure has little effect on the pressure fluctuation.
