F091002 Direct Simulation of Aero-acoustics by the Finite-Difference Lattice Boltzmann Method

Abstract

Direct simulations of sounds by the finite difference Lattice Boltzmann Method are briefly described. Two types of models for compressible fluids are introduced, and some simulation results are shown. A model for two-phase flow, air and water, is also introduced and sound in the air and under water sound are directly simulated.
