The exact solution to the axisymmetric acoustic problem of the interaction of a plane wave with a spherical liquid bubble immersed into a dissimilar fluid in a cylindrical cavity is obtained. To satisfy all boundary conditions, the general solution is expanded into a series of normal modes in the coordinate systems fixed to the bubble and cavity, and the expressions of cylindrical wave functions in terms of spherical wave functions are used. The problem is reduced to an infinite system of algebraic equations solved by reduction. The obtained numerical results describe the pressure and velocity fields in the vicinity of the bubble as functions of frequency, fluid characteristics, and geometric parameters of the mechanical system. The strength of acoustic radiation acting on the bubble is calculated and its features at some frequencies of the wave are shown. [ABSTRACT FROM AUTHOR] |
