【摘要】 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。更多还原

【Abstract】 A CH ion concentration sensor and its measuring system is applied to investigating the influence of low pressure on heat release and pressure fluctuations in two-phase mixture turbulent combustion.The results show that the combustor geometry determines its natural frequency.The chemical reaction zones move upstream as the pressure increases.When a vaporization stabilizer is used in the combustor,equivalence ratio has a less effect on the pressre fluctuation in the low pressure combustion.更多还原
