Abstract: For application of lattice Bohzmann method (LBM) in aeroacoustics field, four fundamental acoustic cases are simulated. Sound waves propagating with planar source and single point source are used to investigate reliability of LBM in aeroacoustics. Capability for reflecting waves is then investigated with diffraction and interference. Doppler effect is simulated to illustrate coupled acoustics and flows. In all cases, simulated acoustics is found in good agreement with analytic solutions. It shows that LBM has good performance in computational aeroacoustics field.

Key words: areoacoustic, lattice Bohzmann method, wave propagation, Doppler effect
