Abstract

In this paper, we present some applications of the finite difference lattice Boltzmann method (FDLBM) to direct simulations of fluid dynamic sound. Two-particle model is used to simulate two-phase flows, and introducing a fluid elasticity the sound propagation inside the liquid is recovered. The sounds generated by bubbles and water drop collision on the shallow water and on deep water are successfully simulated. Keywords: fluid dynamic sound, lattice Boltzmann method, two-phase flow, underwater sound ,bubble, water drop.
