Radiation Impedance of a Small Vent
Application ID: 141041
This model computes the specific acoustic radiation impedance of a very small circular vent in a flanged configuration. The model includes thermoviscous losses. The radiation impedance is fitted using a simple RL circuit which gives a simple lumped representation.
The results are used in the Balanced Armature Transducer — Frequency Domain Analysis and the Balanced Armature Transducer — Time Domain Analysis models.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
