A hydrodynamic nonlinear model of bubble liquid (part II)

The basic principles of construction of bubble hydrodynamics are formulated, and the hydrodynamic equations for a bubble liquid are obtained in [1]. The fluxes involved in the conservation laws have components invariant under the Galilei transform. The present paper is a continuation of [1] and proposes a hydrodynamic theory of bubble liquid without the invariant fluxes. In this sense, uniqueness of the equations of motion based on the principles presented in [1] is determined. The dispersion relation characterizing sound vibrations is limiting for the dispersion relation from [1]. Irreversible fluxes of the dissipative model do not differ from the fluxes obtained in [1].
