  • Acoustic Wave Propagation Analysis using Linearized Lattice Boltzmann Method

抄録

In this study, acoustic propagation is computed based on lattice Boltzmann method (LBM). Linearized form of lattice Boltzmann equation (LBE) is used as a governing equation in order to capture the small acoustic perturbation. Additionally, implementations of farfield boundary condition and a monopole sound source are described in detail. The current code has a potential to solve acoustic propagation from non-compact body, including non-uniform mean flow effect and reflection at the wall. Several benchmark problems are solved, and current results show good agreement with the analytical results.
