Acoustic Reflection Analyzer for a Water-Sediment Interface
Application ID: 30881
Analyzing acoustic reflections at surfaces of various structures is important for many engineering disciplines. The Acoustic Reflection Analyzer for a Water-Sediment Interface app shows one such system where the analysis has relevance for underwater acoustics and sonar applications.
The app analyzes the reflection and absorption coefficients of plane acoustic waves, scattering off of a water-sediment interface at different frequencies and angles of incidence. Moreover, the random-incidence absorption coefficients are determined for the studied frequencies.
To describe the water-sediment system, the app uses the ability of the Poroelastic Waves interface in COMSOL Multiphysics to model the coupled acoustic and elastic waves in any porous substance (Biot's theory).
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 Specification Chart and make use of a free evaluation license.
