摘要

考虑了烃类混合物冷焰燃烧的随机模型。对于该三维模型，研究了确定性模型只有一个平衡吸引子的参数区内大振幅振荡的噪声激励。通过对脉冲间隔的统计，揭示了一种反相干共振现象。为了估计引起激振的噪声的阈值强度，采用了随机灵敏度技术和主方向法。

Stochastic generation of oscillations in the 3D-Model of cool-flame combustion of a hydrocarbon mixture

The stochastic model of cool-flame combustion of a hydrocarbon mixture is considered. For this 3D model, noise excitement of large-amplitude oscillations in the parametric zone, where the deterministic model has a single equilibrium attractor, is studied. By statistics of interspike intervals, a phenomenon of anti-coherence resonance is revealed. To estimate threshold intensities of noise that causes excitement, stochastic sensitivity technique and method of principal directions are applied.
