| 摘 要： | 为了揭示离心力对内燃波转子火焰传播特性的影响,建立了内燃波转子燃烧过程的简化模型,数值模拟了不同离心力场强度下波转子通道内的燃烧过程。研究结果表明,离心力只在一定范围内对火焰传播起到加速作用,且这种影响与预混气当量油气比Φ![]() ![]() 有关,当Φ=1.0![]() ![]() 时,作用范围为［0～250g］,在Φ=0.6![]() ![]() ,0.8![]() ![]() 时,作用范围为［0～700g］;离心力场对内燃波转子火焰传播特性的影响机制是导致火焰锋面变形,进而引起火焰传播速度变化。

| Abstract: | A simplified model of the combustion process of the internal combustion wave rotor is established, and the combustion process in the rotor passage with different centrifugal force field intensity is numerically simulated. The results show that the centrifugal force can accelerate the flame propagation only in a certain range, and the effect is related to the ratio of premixed gas to oil The influence of Centrifugal force field on the flame propagation characteristics of the internal combustion wave rotor is caused by the deformation of the flame front and the variation of the flame propagation velocity. The research results lay a foundation for further research and application of the internal combustion wave rotor. |
