VA One Vibro-Acoustics

This FE model is representative of a HVAC cylindrical duct.

The aim of this model is to predict average sound pressure along the duct by recovering data on several locations of the duct.

The duct is modeled by an FE acoustic cavity which is bounded by a velocity constraint on the inlet and air impedance on the outlet.

Several Data recovery faces are associated to the duct to apply boundary conditions and recover pressure data.
