Application ID: 1375
Fluid acoustics coupled to structural objects, such as membranes or plates, represents an important application area in many engineering fields.
Some examples are:
• Acoustic sensors
• Nondestructive impedance testing
• Medical ultrasound diagnostics
This model provides a general demonstration of an acoustic fluid phenomenon in 3D coupled to a solid object. In this study, the solid object is a capped, hollow aluminum cylinder filled with and immersed in water.
The acoustic pressure created by a source inside the cylinder impacts on the cylinder walls. The frequency response from the solid object is calculated, and the information is fed back to the acoustics domain so that the wave pattern can be analyzed.
This model example illustrates applications of this type that would nominally be built using the following products:Acoustics Module
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 Specification Chart 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.
