To illustrate the basic thermoacoustic cooler of a thermoacoustic cooler, the thermodynamic cycle of the gas parcels is simplified as a Brayton cycle consisting of two adiabatic steps and two constant-pressure steps by Thermoacoustic cooler and Swift [ 1 ].

Thermoacoustic heat engine - Wikipedia

But the analysis shows that the parcel has always contacted with the plate as it oscillates alongside the plate. The thermoacoustic cooler steps are not tally with the fact. In this paper, a new thermoacoustic cooler model will be adopted to study the thermoacoustic refrigeration cycle.

Therefore, it is crucial to analyse and increase the cooling load and the COP for improving the performance of a thermoacoustic cooler. Several thermodynamic quantities of the thermodynamic cycle are mostly derived thermoacoustic cooler using the thermoacoustic cooler ideal gas equation of state.

The basic ideas about the behaviours of gas cycles are based on the results of these derivations.

But when the gas temperature is low enough or density is high enough, the thermoacoustic cooler will deviate its classical behaviour [ 5—7 ]. This deviation results from the quantum degeneracy of gas particles.

Under the conditions, thermoacoustic cooler gas called quantum gas obeys the Bose—Einstein or Fermi statistics.

For thermodynamic cycles at low thermoacoustic cooler, the quantum degeneracy of the working gas has thermoacoustic cooler be considered. Owing to the fact, the effect of the quantum degeneracy on the performance of a thermodynamic cycle has become one of the interesting research subjects.

Interference can occur between two waves traveling in opposite directions at certain frequencies. The interference causes resonance creating a standing wave.

Resonance only occurs at certain frequencies called resonance frequencies, and these are mainly determined by the length of the resonator.

The stack is a part thermoacoustic cooler of small parallel channels. When the stack is placed at a certain location in the resonator, while having a standing wave in the resonator, a temperature difference can be measured across the stack.

By placing heat exchangers at each side of the stack, heat can be moved. The opposite is possible as well, by creating a temperature difference across the stack, a sound wave thermoacoustic cooler be induced.

The experimental studies of thermoacoustic cooler.

The first example is a simple heat pump, while the second is a prime mover. Heat pumping[ edit ] To be able to create or move heat, thermoacoustic cooler must be done, and the acoustic power provides this work. Thermoacoustic engine and Thermoacoustic refrigerators.

In a Thermoacoustic engine, thermoacoustic cooler is converted into sound energy and this energy is available for the useful work. In this device, heat flows from a source at higher temperature to a sink at lower temperature.

In a thermoacoustic refrigerator, the reverse of the above process occurs, i.
