Resonator coiling in thermoacoustic engines

The Journal of the Acoustical Society of America, 1995
Coiling the resonator of a thermoacoustic engine is one way to try to minimize the engine’s size. However, flow in bent pipes is known to alter the fluid flow pattern because of centrifugal forces. Theory and measurements will be presented on the energy dissipation caused by oscillating flow in curved pipes.

Introduction to Thermoacoustic Engines and Refrigerators

Noise Control and Acoustics, 2001
Abstract Glassblowers observed the generation of sound in the presence of temperature gradients over one hundred years ago. It was less than twenty years ago that the reverse process — the use of high-amplitude sound to produce refrigeration — was first demonstrated. Due to the discovery of the “hole-in-the-ozone” and the ratification of

Unconventional thermoacoustic heat engines

The Journal of the Acoustical Society of America, 2006
During 1988 to 1994, John Strachen and Harold Aspden demonstrated an all-solid-state thermoelastic cooler which was 0.5 cm thick and a few centimeters in length. With 7.2 V dc applied across the device, it drew 6.3 W of electrical power and produced 13.7 W of cooling power with a 20<th>°C temperature drop.

Radial wave thermoacoustic engines

The Journal of the Acoustical Society of America, 1992
Thermoacoustic heat engines are used to produce sound from heat and to transport heat using sound. Most previous work has concentrated on engines in plane-wave resonators. This paper is about the analysis of engines in radial mode cylindrical resonators.
