Abstract
When combustion instability occurs, the pressure oscillation will result in periodic change, not only in the injector flow rate but also in the atomization characteristics of the injector. In this work, atomization characteristics of swirl injectors under a standing-wave acoustic field were studied experimentally; the effects of acoustic pressure and injector position were analyzed on atomization and injectors characteristics in the critical state. It was found that under the same acoustic pressure, the effect of the acoustic field at the velocity antinode was stronger than the effect at the acoustic intensity antinode; and there was little effect at the acoustic pressure antinode. The hysteresis phenomenon of the spray field was also found in low flow rate cases in the acoustic field. The effects of the flow rate and liquid viscosity on atomization characteristics were analyzed, and the behavior of the Faraday wave was observed and studied during the experiment.
