Abstracts:

This work is the continuation of the experimental study of hydrodynamic processes, occurring at injection of cryogenic liquid into water. The processes accompanying phase transition at liquid nitrogen mixing with water were registered during these studies. It is shown that the amplitude of pressure jumps, developed during these processes, is within the range from 1.4 to 5.3 MPa. The pressure depends on a change in different conditions of injection, such as the temperature of working environment, free surface area, etc. The optic registration of liquid nitrogen injection into water revealed the structure and stages of the developing process. It is shown that at the external boundary of a vapor cylindrical bubble, active turbulent mixing occurs, and this should be taken into account, when developing the mathematical model of the process. The ice-like crystalline structures are observed at the gas-water interface. These results can be useful for development of a new method of gas hydrate production, based on the shock-wave technique.
