Stochastic Generation of Oscillations in the 3D-Model of Cool-Flame Combustion of a Hydrocarbon Mixture

Abstract

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. © 2023, Institute for Problems in Mechanical Engineering, Russian Academy of Sciences.
