The features of ultrasonic spraying process in a thin layer in the pressurized chamber. Experimentally proved that at the change of pressure in the chamber the size of the nebulized liquid aerosol does not change, that confirms analytical dependence of calculation of diameter of drop. Two cases are presented placing an ultrasonic disperser chamber pressurized. Experimentally and analytically proved that the performance of the ultrasonic spraying process decreases linearly with increasing chamber pressure. The features of ultrasonic atomization process in a thin layer during placement of the dispersant in a fully pressurized chamber and its placement in the partial chambeReferences
