| 摘 要： | 基于二维Euler方程,结合高精度Roe/HLL(Harten-Lax-Van Leer)混合格式与自适应网格加密技术,对引射模态下的双管爆轰非定常单次引射复杂流场进行了数值模拟.结果分别描述了方管爆轰波喷出及引射管内二次爆轰波的传播过程.双爆轰波喷出爆轰管后,以欠膨胀射流形式向外传播,同时,它们相互作用延长了引射管尾...

| Abstract: | Based on two-dimensional Euler equations,and in combination with the high-resolution hybrid Roe/HLL(Harten-Lax-Van Leer) scheme and adaptive mesh refinement method,numerical simulations of single ejection driven by two pulse detonation engines(PDE) were performed.The results show the propagation processes of the ejection of the primary detonation and the secondary detonation induced inside the ejector.After two detonation waves are ejected out,they propagate in the form of unexpanded jet flow,and interact w... |
