Immersion Ultrasonic Testing Setup
Application ID: 78801
This tutorial showcases the principles of the immersion ultrasonic testing technique. A search unit placed in a water tank sends an ultrasonic pulse signal that scatters off a solid object. Part of the signal is reflected back to the search unit by the object and possible flaws in it. By analyzing the reflected signal the position of the object and the flaws can be determined.
The model uses the Pressure Acoustics, Time Explicit and the Elastic Waves, Time Explicit physics interfaces. The acoustic-structure interaction is established by using the Pair Acoustic-Structure Boundary, Time Explicit multiphysics coupling. The model takes advantage of a geometry assembly and a nonconforming mesh.
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 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.
