Abstract: A new centrically slit flame holder(CSFH) for afterburner is presented,and the experimental research work shows that it has simpler structure,lighter weight, higher combustion efficiency,and better stability.The PIV technology was applied to study flow fields of the flame holder wake,which reveals that the good combustion characteristics depend on the recirculation zone structure of slit flame holder and the particular vortex shedding patterns.
