Ballistic imaging in the near-field of an effervescent spray
We have investigated liquid breakup mechanisms in the near nozzle region of a high-pressure effervescent atomizer using ballistic imaging. This technique has revealed various breakup regimes depending upon total flow rate and the gas-to-liquid ratio (GLR). At low total speeds, the jet does not exhibit the wide spread angle and rapid breakup for which effervescent sprays are known, even at high GLR
