ABSTRACT

Specific features of evolution and decay of pulse disturbances in vapor-liquid mixtures of a bubble structure at high initial static pressures are studied. It is shown that with an increase in an initial pressure leading to a decrease in heat of vapor generation, a rarefaction zone which may have an oscillatory structure is formed behind the peak of compression. A similar picture is observed with a decrease in heat of vapor generation of the medium or with an increase in the intensity of phase transitions that takes place, e.g., in transition from water to liquid helium.
