NUMERICAL MODELLING OF THERMOACOUSTIC PHENOMENON AS CONTRIBUTION TO THERMOACOUSTIC ENGINE MODEL

TASK Quarterly, 2010
The presented paper shows our first step into the numerical modelling of the thermoacoustic phenomenon. The thermoacoustic effect has a great application potential, for instance, in thermoacoustic engines or thermoacoustic mixture separation.

Study on Coupling in a Thermoacoustic Driven Pulse Tube Refrigerator

Zhileng xuebao, 2018
Thermoacoustic-driven pulse tube refrigerators are usually coupled directly or by long tubes called acoustic amplifiers. With these coupling methods, the efficiency of the whole system is quite low because of the nonideal acoustic field and flow losses ...

Experimental Investigation of Thermoacoustics and High-Frequency Combustion Dynamics with Band Stop Characteristics in a Pressurized Combustor

Energies
In combustor systems, thermoacoustic instabilities may occur and must be avoided for reliable operation. An acoustic network model can be used to predict the eigenfrequencies of the instabilities and the growth rate by incorporating the combustion ...
