Abstract

Numerical simulations of the collapse of bubbles (or cavities) are shown, using the finite difference method. Simulations were made using: water, benzene, glycerin, and mercury. Pressure fields values are calculated in an area of 800 x 800 mm, first for the case of one bubble under the hypothesis of spherical symmetry, and then for the case of four bubbles, where the spherical symmetry no longer exists. Results are shown as pressure curves in the plane. The existing method doesn’t take into account the physical properties of the fluid and it is available for one bubble only.
