摘要
基于带化学反应的Navier Stokes方程和有关的热力学和反应动力学数据,利用改进的VLS格式,对甲烷 空气混合物中激波与火焰的相互作用进行了数值模拟。根据计算结果,讨论了激波掠过火焰时的变形、分叉和发展,以及激波作用下火焰的失稳、变形、破碎和相应的带旋涡的流场。
Based on the Navier-Stokes equations coupling with chemical reactions, the phenomena of shock-flame interactions in the methane-air mixture are numerically studied by using VLS scheme. The evolution of flow patterns are presented at different interaction stages and the bifurcate shock waves, distorted flame fronts and induced vortices are discussed according to the calculated results.
