Investigating the impact of ultrasonic exposure frequency and reduced pressure on the liquid evaporation process

Theoretical and experimental investigations of the ultrasonic exposure (USE) frequency impact on the liquid evaporation process are carried out. Investigations were carried out under reduced pressure in a vacuum chamber. A refined physico-mathematical model of the USE thermodynamic process is developed. The dependences of the change in mass and temperature of various liquids (distilled water, alcohol mixture, kerosene TS-1) on the USE frequency and external pressure are obtained. The effect of a sudden liquid "explosion" at certain USE frequency and external pressure values is discovered. The results of physical and mathematical modeling are obtained as the dependence of the change in liquid temperature on the USE frequency and external pressure. The results of physical and mathematical modeling and experimental research are analyzed and compared. The obtained results can be used for drying various materials and cleaning surfaces. (paper)
