摘要

The spray-combustion flow of a side-dump ramjet combustor attached symmetrically with four inlets is analyzed numerically by using a modified KIVA-3 computer code. Numerical results obtained from the present study reveal that open circulating flows, exhibiting three-dimensional structures, occur in the region between the jet-impingement point and the dome head, and pairing vortexes appear in the surroundings of impinging jets. Injector positions are found to have strong influences on fuel distributions and flame structures, while effects of injection cant-angles on the flame structure are relatively limited. Injectors installed on the inlet-duct wall near the dome are responsible for the fuel distribution in the dome region, since the fuel penetration depth is short under high-speed air-stream in the inlet. Those on the opposite wall of inlet ducts, however, dominate the fuel distribution in the downstream region of the combustor. The flame structure is closely related to the fuel distribution and the local stoichiometry.
