Simple Thermoacoustic Engine
Application ID: 107461
This is a model of a simple thermoacoustic engine that includes a thermal stack to convert thermal energy to acoustic energy. The model is set up using two approaches:
1) Using a linear perturbation (acoustic) approaches solving the fluid motion with theThermoviscous Acoustics, Transientinterface.
2) Using a full nonlinear approach using theNon-Isothermal Flowmultiphysics interface.
The model studies different stable, decaying, and amplifying configurations of the engine. The model also shows that some nonlinear effects at high acoustic velocities are not caught in the acoustics model which is based on perturbation theory. TheThermoacoustic Engine and Heat Pumptutorial extends the current model to also include a thermoacoustic heat pump.
