Acoustics of a Pipe System with 3D Bend and Junction
Application ID: 40831
This tutorial shows how to model the propagation of acoustic waves in large pipe systems by coupling the Pipe Acoustics interface to the Pressure Acoustics interface. The tutorial is set up in both the time domain and the frequency domain.
1D pipe acoustics is used to model the propagation in the long straight pipe portions. A 3D model of a pipe junction and pipe bend is coupled to the 1D pipe model in order to model these parts in detail.
This kind of model can be used to model and predict the response of pipe systems, such as when detecting leaks or deformations, for example, and is relevant in the oil and gas industry and in water delivery pipe systems.
This model example illustrates applications of this type that would nominally be built using the following products:Acoustics Module Pipe Flow 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.
