Study of a thermoacoustic-Stirling engine [PDF]
The Journal of the Acoustical Society of America, 2008 During the last decade most efforts in thermoacoustics have been focused on the development and understanding of the traveling-wave thermoacoustic systems. These systems get much attention because they employ the inherently efficient Stirling cycle.
