Perforated Media

The modeling of a perforated media is supported by the use of one of the following models:

  • Johnson-Champoux-Allard Equivalent Fluid

  • Delany-Bazley Equivalent Fluid

  • Miki Equivalent Fluid

  • Complex Impedance and Propagating-Constant Equivalent Fluid

  • Complex Density and Velocity Equivalent Fluid

See the Equivalent Fluid Model of Perforated Material section of the Mechanical APDL Acoustic Analysis Guide for a more detailed description of the above properties.
