Abstract

In order to study the phenomenon and mechanism of low-pressure atomization, a test rig of low-pressure jet nozzle atomization was built. Flow, atomization angle and atomization characteristics of atomization particle size of low pressure fine atomization nozzle aperture size 0.3mm, 0.5mm, 0.8mm and 1.0 mm in the pressure below 0.15MPa are researched by using high-speed photography equipment and MATLAB software to collect and analyze aerial images . The results show that the nozzle flow is positively correlated with the atomization pressure. The atomization angle increased with the increase of the pressure and is stable between 60 degrees and 80 degrees. the jet nozzle will appear in the axial direction after the dispersion of the phenomenon at the pressure of 0.08MPa,; atomization particle size and atomization pressure was negatively correlated, and smaller diameter nozzle at a smaller pressure atomization has larger particle size. The study of this paper provides guidances for the application of atomization and humidification under low pressure conditions.
