Abstract
The process of gas bubble fragmentation and dissolution with the formation of freon-12 hydrate behind shock wave of a moderate amplitude in water with gas bubbles was investigated using a shock-wave technique. The kinetic mechanism of gas hydrate formation and the time dependence of gas content for all the gas contained in gas bubbles to turn into the gas hydrate state were derived. The bubble dimensions were determined with additional optics through optical windows. The results show that the flocculent hydrate film formed on the bubble surface does not prevent passage of liquid-solid interface leading to the formation of new hydrate films. The results also show that the dissolution and formation of hydrate behind a shock wave of a moderate amplitude is due to fragmentation of gas bubbles, which leads to sharp enlargement of the interface and a decrease of the size of gas inclusions.
