Liquid sheet disintegration at high pressure: An experimental approach

摘要: Abstract The primary atomization was studied in a 300 μm thickness water sheet, generated by planar airblast atomizer. research novelty consisted increasing the airflow absolute pressure from atmospheric conditions to 6 bar. experimental techniques employed included Oscillometry Laser Intensity Reflexion (ORIL), Doppler Velocimetry (LDV) and flow visualization fast video camera. mechanisms, described literature at environments, were observed high conditions, for constant momentum flux ratio. Furthermore, new mechanism values of this Finally, dimensionless relations have been proposed global oscillation frequency, minimum air velocity, break-up distance transversal wavelength.
