Porous Material Characterization from Impedance Tube Measurement
Application ID: 142771
This app is an example of how the poroelastic properties of a porous material can be determined based on measurement done with an impedance tube and parameter estimation.
Being able to determine the characteristics of a porous material from a single and simple measurement opens the door for simulations with accurate boundary conditions. The parameters obtained through this app can be used directly in other models with the Poroacoustics feature.
The porous material investigated here was provided by ROCKWOOL A/S, and the impedance tube measurement was performed by Hottinger Brüel & Kjær A/S.
This application 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.
