Аннотация:
The paper studies the dynamics of pressure waves in a pipe with water containing a water-air bubble cluster in the form of a hollow cylinder. A system of macroscopic equations for the laws of conservation of masses, the number of bubbles, momenta, and pressure in bubbles was used in the approximation of cylindrical symmetry. This system of equations was solved using an explicit scheme. The dependence of the maximum value of the pressure amplitude recorded in the pipe on the geometrical parameters of the cluster and pipe, as well as on the amplitude of the initial impact, was analyzed. It is shown that for the case of a bubble region in the form of a solid cylinder, the amplitude of the wave signal behind the bubble zone is several times higher than the amplitude for the case of a hollow cylindrical cluster.
