The Estimation of Trapped Modes in a Cavity–Duct Waveguide Based on the Coupling of Acoustic and Flow Fields

The Estimation of Trapped Modes in a Cavity–Duct Waveguide Based on the Coupling of Acoustic and Flow Fields

Trapped modes that exist in the waveguide have different engineering applications. Excited acoustic modes are due to the interaction between acoustic and flow fields. To further study the influence of nonpotential flow on trapped modes for a two-dimensional cavity–duct system, a numerical simulation...
