摘要/Abstract

摘要： 为研究煤油燃料旋转爆轰波的起爆与传播特性，开展气体-液体两相旋转爆轰发动机实验研究。旋转爆轰发动机环形燃烧室内径120 mm、外径153 mm、长240 mm，煤油为燃料、富氧空气为氧化剂，通过氢气/氧气微小型脉冲爆轰发动机进行点火；基于燃烧室内的高频压力，分析气体-液体两相旋转爆轰波的起爆过程、传播特性以及发动机的工作特性。实验结果表明：混合物的反应活性至关重要，当氧化剂中氧含量偏低时，混合物反应活性低，旋转爆轰波将无法起爆，直至氧含量增加到39.2%，才能形成自持传播的爆轰波；爆轰波成功起爆后均以双波对撞模态传播，波速为815~ 920 m/s；在贫油条件下，爆轰波传播速度随着当量比提高呈增加趋势；当空气质量流量大于822 g/s时，发动机基本以缓燃形式工作。

Abstract: A rotating detonation engine（RDE） was test to study the initiation and propagation characteristics of kerosene fuel rotating detonation wave. The inner diameter, outer diameter and length of RDE annular combustor are 120 mm, 153 mm and 240 mm, respectively. It is ignited by a hydrogen/oxygen micro-pulse detonation engine with kerosene and oxygen-rich air used as fuel and oxidant, respectively. The initiation process and propagation of gas-liquid two-phase rotating detonation wave, and the operation characteristics of engine are analyzed from high-frequency pressure signals in combustor. The test results indicate that the reactivity of mixtures plays an important role on the initiation of detonation wave. When the content of oxygen in the oxidant is low, the reactivity of the mixture is low, and the rotating detonation wave fails to be initiated. It is until the oxygen content increases to 39.2% that the rotating detonation wave can be formed. The rotating detonation wave always propagates in two-wave collision mode with the wave velocity range of 815-920 m/s after successful initiation. The velocity of detonation wave tends to rise with the increase in equivalence ratio under lean fuel condition. The engine mainly works in a deflagration mode when the mass flow rate of air is more than 822 g/s. Key
