Underwater Ray Tracing Tutorial in a 2D Axisymmetric Geometry
Application ID: 44711
When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics interface. It illustrates the intensity and phase calculation in graded media (speed of sound profile) including frequency-dependent attenuation in seawater (using a semiempirical model from literature). Two different boundary reflection models are used for the sea surface and the sea bottom.
All material properties and reflection models can be analytical functions or imported model data. They can depend on frequency and angle of incidence.
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 Spezifikationstabelle 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.
