查询词典 vortex flow

In this paper, experimental study (Ma=2.0 of cold flow) on a scramjet combustor model without combustion was carried on direct-connected facility. The effects of inflow parameter, length of isolator and back pressure on combustor and isolator flow field were analyzed and compared. The flow field of combustor was simulated with CFD software and the experimental results were compared.
