Numerical analysis of 3-D sound propagation in circular ducts with circumferential modes at inlet

    Graphical Abstract
    • Abstract
  • Numerical analysis of three-dimensional sound propagation in soft-soft or soft-hard circular ducts with circumferential and axial modes of sound sources at inlet has been carried out. In this paper, the numerical method and examples are presented, and the effect of circumferential and axial modes on numerical results is also discussed.
