Abstract
The incoming air temperature was within the range of 773-1073K. The incoming flow Mach number ranged from 0.20-0.32. The results showed that, the lean blow-off (LBO) fuel/air ratio of integrated cavity-based strut flameholder (ICBSF) was within the range of 0.0013-0.0027 and had a wide lean blow-off limit because of the cavity structure favorable for evaporation and atomization of fuel. LBO fuel/air ratio of ICBSF increased with the increase of incoming flow Mach number and decreased with the increase of flow temperature, similar to that of conventional bluff-body stabilizers. When the temperature of incoming flow was significantly increased, the influence of the incoming Mach number on fuel/air ratio of ICBSF was weakened; similarly, when the incoming Mach number was significantly increased, the influence of the inflow temperature was also weakened.
