【摘要】 基于带化学反应的三维Euler方程,对环形燃烧室内旋转爆轰的传播过程进行了数值模拟,可燃气为等当量比的氢气/氧气混合物,化学反应模型采用8组分48个反应的基元化学反应。结果表明,旋转爆轰可以稳定传播,具有不同于传统CJ爆轰的结构,其三维爆轰波阵面具有非受限的特征。更多还原

【Abstract】 Based on three-dimensional reactive Euler equation with hydrogen/oxygen mixture of eight-species,forty-eight-reaction mechanism,the rotating detonation in the annular combustor was simulated numerically.The results shows that rotating detonation wave can propagate steadily,which is different from classic CJ theory.Three-dimensional rotating detonation structure has the characteristics of non-restriction.更多还原
