Description

technical field

[0001] The invention relates to a thermoacoustic power generation device, in particular to a power generation system driven by traveling wave thermoacoustics. Background technique

[0002] The traveling wave thermoacoustic Stirling engine has the advantages of high efficiency, good energy adaptability, and no moving parts. A traveling-wave thermoacoustic Stirling engine can efficiently convert various heat sources (including waste heat) into mechanical work, and a linear generator can realize the conversion of mechanical energy into electrical work.

[0003] For a linear generator, the sound work input into the generator is given by the following equation:

[0004] W = 1 2 Re [ p ~ U * ~ ] = 1 2 | ...
