Background:

Thermoacoustic engines convert heat to sound.
Piezoelectric transducers convert sound to electricity.
Thermoelectric generators offer limited efficiency for waste heat recovery.

Purpose of the Study:

To predict the efficiency of a thermoacoustic waste heat power conversion device.
To assess the competitiveness of thermoacoustic generators against thermoelectric devices for small-scale power generation.

Main Methods:

Simulated a simple, high-frequency, air-filled, standing wave thermoacoustic generator using a low-amplitude approximation.
Modeled the acoustic impedance of a piezoelectric transducer using an equivalent circuit model based on its properties.

Main Results:

The thermoacoustic generator design is predicted to achieve approximately 10% of Carnot efficiency.
This performance level is competitive with existing thermoelectric generators.

Conclusions:

A simple thermoacoustic device shows promise for efficient waste heat power conversion.
Further development could position thermoacoustic generators as a viable alternative to thermoelectric technologies.
