Numerical Analysis of Acoustic Wave Propagation in Enclosures via Lattice Boltzmann Method: Impact of Geometry, Viscosity, and Source Characteristics

چکیده مقاله

This study investigates acoustic wave propagation in two-dimensional enclosures, addressing critical applications in noise mitigation, architectural acoustics, and medical imaging. Despite previous research, a detailed parametric analysis of wave interference, dissipation, and stability remains lacking. A direct lattice Boltzmann method framework models acoustic wave behavior, focusing on geometric configurations, medium viscosity, and source parameters. Two oscillating local sources generate waves, while two receivers capture density fluctuations. For accuracy, the model is validated against established numerical benchmarks. The effects of varying aspect ratios (
