Abstract
A mathematical model is developed for the formation of the bubbles in a container with a liquid under acoustic-vacuum exposure. The bubbly liquid layer is investigated in the form of a solid body with an elastic modulus depending on the following parameters: the acoustic exposure, the velocity of the bubbles, and the change in their volume. To investigate the frequency characteristics of the liquid with bubbles in the system "vacuum chamber - cupola - bubbly liquid layer - the bottom of the container with acoustic exposure", the liquid layer is considered in the form of a mechanical pendulum. The conducted mathematical and physical experiments confirmed resonance in the liquid evaporation process at certain parameters of acoustic-vacuum exposure. In particular, the differences between theoretical and experimental values were as follows: in the temperature of gas up to 2%, in the temperature of a liquid up to 1.3%, in the pressure of a vapor of a liquid up to 30%, in the time of occurrence of a resonance regime up to 1%.
