Organ Pipe Design
Application ID: 14729
The Organ Pipe Designer allows you to study the design of an organ pipe and then play the sound and pitch of the changed design in a user-friendly app. The pipe sound includes the effects of different harmonics with different amplitudes.
The organ pipe is modeled using the Pipe Acoustics, Frequency Domain interface in COMSOL Multiphysics. The simulation app allows you to analyze how the first fundamental resonance frequency varies with the pipe radius and wall thickness, as well as with the ambient pressure and temperature.
Using the app, you can find the full frequency response, including the fundamental frequency and the harmonics. With a Java® code written method, the app will detect the location and amplitude of all harmonics in the response, thus extending the analysis beyond the built-in functionality of the COMSOL Multiphysics user interface.
This application 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 Tabela de Especificações 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.
