Absorptive Muffler Designer
Application ID: 30691
Mufflers are used to attenuate noise emitted by a combustion engine, for example, and should typically perform well in a specific frequency range. Attenuation is measured through transmission loss, which gives the damping in dB as a function of frequency.
The Absorptive Muffler Designer simulation app is used for studying and designing a simple resonant muffler with a porous lining. With the app, you can perform an analysis of both inductive and resistive damping in a muffler of your choosing.
The app enables you to study the results after changing the dimensions of the muffler, the ambient working conditions, and the material properties of the porous liner.
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. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
