An experimental system employing hot jet ignition was used to investigate the effects of hot jet equivalence ratio, jet flow rate, and premixture equivalence ratio on the ignition and flame propagation characteristics of a single-channel wave rotor combustor. The study revealed that the hot jet equivalence ratio and jet flow rate exert a notable influence on the initial flame front position. The ignition delay time for the wave rotor combustor remains approximately 4 ms within the tested parameter range, regardless of variations in the jet conditions. The stable flame propagation velocity primarily depends on the premixture equivalence ratio within the wave rotor channel, with optimal flame propagation achieved at a specific ratio. Additionally, the premixture equivalence ratio inside the wave rotor channel significantly impacts the shape of the flame front. |
