Thermoacoustically driven triboelectric nanogenerator: Combining thermoacoustics and nanoscience
Applied Physics Letters, 2017A thermoacoustic heat engine (TAHE) is a type of regenerative heat engine that converts external heat into mechanical power in the form of an acoustic wave with no moving mechanical components. One significant application of the TAHE is the generation of electricity by coupling an acoustic-to-electric conversion unit such as a linear motor or a ...

rf testbed for thermoacoustic tomography
Review of Scientific Instruments, 2009Thermoacoustic signal excitation is a function of intrinsic tissue properties and illuminating electric field. De-ionized (DI) water is a preferred acoustic coupling medium for thermoacoustics because acoustic and electromagnetic waves propagate in DI water with very little loss. We have designed a water-filled testbed propagating a controlled electric

Thermoacoustic phenomena, involving the generation of sound by fluctuating heat addition have been studied for over two centuries. They are most familiar in the form of such laboratory devices as the Sondhaus tube and the Rijke tube and in the destructive instabilities that can occur in combustion systems. Now, Albert Migliori and Greg Swift at the Los

Thermoacoustic engines, or acoustic heat engines, are energy-conversion devices that achieve simplicity and concomitant reliability by use of acoustic technology. Their efficiency can be a substantial fraction of Carnot’s efficiency. In thermoacoustic prime movers, heat flow from a high-temperature source to a low-temperature sink generates acoustic ...

Numerical optimization of a novel thermoacoustically driven thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 1997Previous modeling work on a novel heat-driven refrigerator has generated overall COP numbers in the range of 0.45 using pure helium gas. The modeled conditions are for commercial or air-conditioning cooling temperatures, with a hot drive temperature of 400 °C.
