| 摘 要： | 凹腔作为促进燃烧室中燃料与来流混合和稳定燃烧的有效手段之一,其研究已引起人们的广泛关注.采用数值模拟方法,探索了圆形超燃冲压发动机燃烧室阻力特性随凹腔结构参数的变化趋势,同时初步考察了飞行攻角对凹腔阻力特性的影响.研究发现,凹腔摩阻相比压阻很小,凹腔时燃烧室的阻力特性主要体现在其压阻上;随着后掠角的增大,热试和冷流状态...

| Abstract: | As one of the most effective methods to promote the fuel and the incoming air in the combustor to mix and combust steadily,the research of cavity has drawn an ever increasing attention.The effect of cavity configuration parameters on drag characteristic of round scramjet combustor was discussed by using numerical simulation method.Meanwhile,the effect of the angle of attack on the drag characteristic of the cavity was investigated preliminarily.The results show that the frictional drag of cavity is much les... |
