摘要
使用有限谱ENO(EssentiallyNon Oscillatory)格式 ,采用V .P .Korobeinikov二步化学反应模型 ,对稀释的化学当量的氢气和氧气混合物中非定常自维持爆轰波进行了二维数值模拟 ,研究了波的产生和演化机理 ,分析了爆轰波的三波结构和传播过程。计算得到的爆轰波参数和结构与以前的计算和实验结果一致。研究表明 :有限谱ENO格式可以成功地模拟非定常自维持爆轰波。
High order finite spectral ENO scheme and two-step reaction model are used to simulate nonsteady detonation waves of stoichiometric hydrogen-oxygen mixture in order to study the development of transverse waves and the evolution of triple-shock waves. Finer structures of detonation waves were simulated and the mechanism of collision and submergence of triple-shock waves were discussed. The obtained characteristics of detonation waves are in good agreement with previous numerical and experimental results. Study shows that high order finite spectral ENO scheme can be used to simulate detonation waves.
