Abstract

Flame distortion induced by shock waves frequently occurs in natural and human activities. To deeply understand the characteristics of flame distortion and combustion, a two-dimensional numerical study of a spherical flame distortion induced by a planar incident shock wave and its reflected wave was carried out for an ethylene/oxygen/nitrogen mixture. And a single-step chemical reaction and high resolution of grid was adopted. It can be found that before the interaction of reflected shock wave with flame, the physical process plays an important role; while after the interaction between reflected shock wave and distorted flame, the reaction heat release rate and flame interface length increase quickly, and the controlling mechanism of flame distortion is transforming to the chemical reaction process. Moreover, the longer reflected shock wave distance induces that the influence of viscosity is stronger.
