Outline of Final Research Achievements

Dynamical equations for non-spherical bubbles and rigid spheres ware derived by the framework of Lagrangian formalism. The derived equations can treat observed behavior of bubbles such as bulk oscillation, shape oscillation, and translation including mutual interaction between the bubbles and the particles.
