Abstract
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.
