Traveling Wave Thermoacoustic Engine
Application ID: 120401
The models simulate the working mechanism of traveling wave thermoacoustic engines. Similary to the standing wave engines, the traveling wave engines make use of the coupling between the fluid motion and the temperature change experienced by the fluid to generate acoustic energy. However, due to the phase difference of the velocity and the pressure, the traveling wave engines have a potential to realize better performance than the standing wave engines.
Two model files are attached to this post: model A whose geometry is a simple loop and model B which was made to imitate an experimental setup. The computational cost of model A is small so each study only takes 1.5 minutes. Model B takes 25-30 minutes to finish, and is in good agreement with the original experimental data.
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.
