Abstract

Previous work showed that acoustic modulation of the dilution-air jets of a small tubular combustor improved performance in that selective and progressive control of the exit plane temperature distribution was possible. Further work on acoustically pulsed free-jet mixing showed that the entrainment coefficient of the jet, and therefore mixing, could be considerably increased, by up to 6 times. The effects correlated well with the amplitude of the jet pulsation velocity Ue. This new work therefore attempts to relate the jet pulsation velocity amplitude to the acoustic power modulating the jet flow thereby leading to a more practical and direct correlation between mixing and acoustic power
