Energy Conservation with Thermoviscous Acoustics

Application ID: 26821

This small tutorial model studies energy conservation in a small conceptual test setup. The model has an inlet and outlet and a Helmholtz resonator with a very narrow neck. The acoustics in the narrow neck are modeled with Thermoviscous Acoustic for a detailed analysis of the thermal and viscous losses.

In order to study and verify energy conservation, the model compares the total dissipated energy in the acoustic boundary layer to the total input minus output power of the system. The two agree.

This model example illustrates applications of this type that would nominally be built using the following products:
