摘要在波纹哈姆雷特近似下，预混火焰发出的声强和频率依赖性与火焰表面的动力学有关。对于湍流火焰刷，其速度，厚度和表面积进行了审查。如果湍流具有柯尔莫哥洛夫谱，则声功率谱变化为ω−5/2。
Abstract The intensity and frequency dependence of sound emitted by a premixed flame are related to the dynamics of the flame surface within the corrugated Hamlet approximation. For the turbulent flame brush, its velocity, thickness, and surface area are reviewed. If the turbulence has a Kolmogorov spectrum the acoustic power spectrum varies as ω−5/2.
