Acoustic Fields in Thin Fluid Layers Between Vibrating Walls and Rigid Boundaries: Integral Method
Original language description
An exact representation, which involves integral formulation, is established for the pressure field inside a thin layer of thermoviscous fluid of finite extent, trapped between a vibrating wall (two-dimensional membrane or plate, herein square) and a planar boundary. Thermo-viscous boundary layer effects and coupling effects are taken into account. The representation would enable analytical estimates to be found for the displacement field of the vibrating wall and pressure variations, then the sensitivity when considering electroacoustic receiver (MEMS microphones, in a large frequency range), among other applications, and would provide results hitherto resolved only by numerical or multi-modal analysis.
