摘要

摘要: 采用12组分、23个化学反应的基元化学反应模型，用5阶加权本质无震荡格式（WENO）、3阶TVD Runge-Kutta格式，对H2-O2-N2混合气体胞格爆轰进行了数值模拟。研究了一维ZND爆轰、自维持爆轰的详细结构以及三波点附近的流动结构。计算结果表明：由横波的压力可以显著促进二维爆轰波波阵面的形成；横波的运动生成三波点，三波点造成了爆轰的自维持传播。

Abstract: Numerical simulation has been performed to study the cellular detonation wave in a mixture using a detailed chemical reaction model with 12 species and 23 elementary reactions and a fifth-order weighted essentially non-oscillatory (WENO) scheme with a third-order TVD Runge-Kutta time stepping method. We study one-dimensional ZND detonation, the detailed structure of self-sustained detonation and flow structure around a triple point. The simulation results suggest that two-dimensional detonation wave front formations are greatly enhanced by the presence of transverse waves. The motion of transverse waves generates triple points, which cause the detonation propagation to become self-sustained.
