Description
Summary:In this work, we study the dynamics of a two-dimensional axisymmetric wave field, which is realized in a pipe containing a spherical cluster of a homogeneous bubbly liquid with a Freon-12 hydrate-forming gas. The “gas-liquid” system in the channel considered in this work is under pressure p0 at the initial moment of time. After a sudden increase in pressure, a bell-shaped pressure wave propagates in the system, which starts the process of formation of gas hydrate in gas bubbles. We assume that at the initial moment of time the hydrate is not formed and the temperature of the liquid remains indifferent. As a result, the dynamics of a two-dimensional axisymmetric pressure wave is shown as it passes through a semi-infinite channel, in which there are spherical bubble clusters with a gas capable of hydrate formation. The theory of nonequilibrium phase transitions in vapor-liquid systems is used as a basis for describing the mechanism of hydrate formation.
