细胞火焰与速度turbulence之间准共振相互作用的详细分析

Detailed analysis of a pseudoresonant interaction between cellular flames and velocity turbulence

V. Karlin

摘要:

这项工作致力于分析上游速度波动对火焰传播速度的影响的微妙细节。调查进行了使用的Sivashinsky模型的流体动力学不稳定的火焰锋的cellarisation。我们确定了稳定传播的火焰,可以显着放大在有限的时间内的扰动。这些扰动被用来模拟上游速度波动对火焰前锋动态的影响,并研究控制火焰传播速度的可能性。

英文摘要:

This work is dedicated to the analysis of the delicate details of the effect of upstream velocity fluctuations on the flame propagation speed. The investigation was carried out using the Sivashinsky model of cellularisation of hydrodynamically unstable flame fronts. We identified the perturbations of the steadily propagating flames which can be significantly amplified over finite periods of time. These perturbations were used to model the effect of upstream velocity fluctuations on the flame front dynamics and to study a possibility to control the flame propagation speed.
