| 1. | Although a dual - mode scramjet ' s configuration is simple and mainly consists of inlet , combustor and wake nozzle , its working process is complicated , especially in the combustor , involving a lot of subjects , including hypersonic aerodynamics , combustion chemistry , etc . the inner flow of a combustor is three - dimensional and complicated , including the interaction of shock wave , deflagration , vortex and boundary layer , and so on
它涉及到高超声速空气动力学、燃烧化学、扩散传质等多门学科；其内部的实际流动是复杂的三维流动过程，充满着激波、膨胀波、燃烧波、各种涡系、附面层及其相互之间的干扰，因此，燃烧室问题是整个发动机研究的关键所在。 |
