Abstract:The mixing process of fuel and oxidizer is a very critical factor affecting the real operating performance of non-premixed rotating detonation combustor. In this paper, a two-dimensional numerical study is carried out to investigate the flow and mixing characteristics of CH 4 /air in combustor with different injection structures. On this basis, the effect of CH 4 /air mixing on the critical ignition energy for forming detonation is theoretically analyzed in detail. The numerical results indicate that injection… Show more
