This paper deals with the eff ect of secondary fl uid injection on oscillatory combustion of a turbulentpremixed fl ame. The eff ect of injection angle and fl uid type on pressure fl uctuations and NOx emissionswas investigated. Characteristics of pressure fluctuations, NOx emissions and flame shapes (OH*chemiluminesence image and OH-PLIF measurement) were discussed. The results indicated that airinjectioninclined at 45 degrees from streamwise direction was effective to stabilize the oscillatoryflame. However, NOx emissions were slightly increased. Furthermore, it was found that secondaryinjection inclined at 90 degrees showed good performance to reduce NOx emissions successfully.
