| 摘 要： | 采用Mac Cormack格式、B-L湍流模型及氢/空气两步化学反应模型,计算了双模态冲压发动机燃烧室在不同来流条件和供油规律下的二维燃烧流场。计算结果表明,在相同来流条件下,供油规律对燃烧室的工作模态有着重大影响;在不同来流条件下,可通过调节供油规律,使燃烧室分别实现亚燃模态和超燃模态。

| Abstract: | MacCormack explicit time-split scheme,BaldwinLomax algebraic turbulence model and two-step global hydrogen-air combustion model were used to calculate the 2D flow field in the bimodal ramjet chamber under different inlet conditions and fuel feeding laws.The results show that under the same inlet condition,the fuel feeding laws have great influence on the operation modality of ramjet chamber,while under different inlet condition,subsonic-combustion and supersonic-combustion modes of ramjet chamber can be respectively realized by adjusting fuel feeding laws. |
