Thermoacoustic Engine and Heat Pump

Application ID: 116071

A thermoacoustic engine is a device with no moving parts that can generate acoustic energy from temperature gradients within the engine. It uses the relationship between the movement of oscillating air and the temperature changes in the air compressed and expanded by the acoustic waves. A similar device has also been devised to generate a temperature gradient by acoustic energy, which is called a thermoacoustic heat pump.

This is a model to simulate a system which couples a standing-wave thermoacoustic engine to a heat pump. The cooling effect by the heat pump is reproduced using acoustic waves excited by the engine. The Simple Thermoacoustic Engine tutorial is used for the geometry of the engine section and simply mirrored for the heat pump section. From this model, it can be confirmed that the reproduction of the heat pump effect requires the consideration of nonlinear terms.
