摘要:
Systems and methods for manipulating acoustic energy are presented. In some embodiments, a combustion zone provides heat to a regenerator using a mean flow of compressible fluid. In other embodiments, a thermoacoustic driver is concentrically disposed within a shell to permit radial heat transfer from the thermoacoustic driver to compressible fluid within the shell, thereby preheating the compressible fluid within the shell. In other embodiments, burning of a combustible mixture within the combustion zone is pulsed in phase with the acoustic pressure oscillations to increase acoustic power output.
摘要:
Thermoacoustic devices are disclosed wherein, for some embodiments, a combustion zone provides heat to a regenerator using a mean flow of compressible fluid. In other embodiments, burning of a combustible mixture within the combustion zone is pulsed in phase with the acoustic pressure oscillations to increase acoustic power output. In an example embodiment, the combustion zone and the regenerator are thermally insulated from other components within the thermoacoustic device.
