超声速气流中轴向涡强化混合及燃烧的数值研究

THE STUDIES OF THE ENHANCEMENTTECHNIQUES OF MIXING ANDCOMBUSTION IN SUPERSONIC FLOWS

通过求解N－S方程，数值计算了扩张圆管内的非平衡流动，并研究了超声速混合和燃烧的强化技术。结果表明，在超声速领域，预旋燃料方式是一种比较有效的强化技术。

The viscous nonequilibrium swirling flows in a divergent duct are simulated by solvingN-S equations, and the enhancement techniques of mixing and combustion in supersonic flows areinvestigated. The results show that the swirling of fuel is an effective enhancement method forsupersonic mixing and combustion.
