Scalability of Thermoacoustic Refrigerator
The Journal of the Acoustical Society of America, 2008The uses of thermoacoustic effect are the conversion of heat onto acoustic wave by thermoacoustic prime mover and pumping heat by acoustic wave using a thermoacoustic refrigerator. Thermoacoustic refrigerator is a good alternative to conventional vapor compression device.

Experimental study and analysis of a thermoacoustically driven thermoacoustic refrigerator
Sādhanā, 2020Experimental investigations are performed on a half-wavelength standing wave type thermoacoustically driven thermoacoustic refrigerator also known as TADTAR. Present TADTAR device conceived to be a quarter wavelength standing wave type thermoacoustic engine (TAE) coupled to a quarter wavelength standing wave thermoacoustic refrigerator (TAR).

Miniaturation of thermoacoustic refrigerators
The Journal of the Acoustical Society of America, 2008The possibility to miniature thermoacoustic refrigerators is theoretically investigated. Both standing-wave and traveling-wave systems are considered. In the consideration of standing-wave refrigerators, a system consisting of a resonator tube (50 cm) with a closed end and a PVC stack (length 5 cm) is taken as a reference.

Thermal Field Measurements of a Thermoacoustically Driven Thermoacoustic Refrigerator
Journal of Thermal Science and Engineering Applications, 2010Thermoacoustic refrigerator is a device that transfers heat from a low temperature medium to a high-temperature medium by using sound energy as work input. We have designed and tested a simplified thermally driven thermoacoustic refrigerator. Our refrigerator is easy to make, uses no moving parts, and has proved to be an impressive illustration of ...

Condensation in a steady-flow thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 2000Condensation may occur in an open-flow thermoacoustic cooler with stack temperatures below the saturation temperature of the flowing gas. In the experimental device described here the flowing gas, which is also the acoustic medium, is humid air, so the device acts as a flow-through dehumidifier. The humid air stream flows through an acoustic resonator.

The optimal stack spacing for thermoacoustic refrigeration
The Journal of the Acoustical Society of America, 2002The characteristic pore dimension in the stack is an important parameter in the design of thermoacoustic refrigerators. A quantitative experimental investigation into the effect of the pore dimensions on the performance of thermoacoustic devices is reported. Parallel-plate stacks with a plate spacing varying between 0.15 and 0.7 mm are manufactured and

Experimental studies on thermoacoustic refrigeration
The Journal of the Acoustical Society of America, 1996Thermoacoustic refrigeration phenomena in a resonance tube were studied experimentally. A horizontal brass tube of 400 mm in length and 40 mm in diameter was closed at one end and attached to the acoustic driver (audio speaker) at the other end. Atmospheric air was enclosed in the tube as a working fluid.

Experimental investigation of an adjustable thermoacoustically-driven thermoacoustic refrigerator
International Journal of Refrigeration, 2018Abstract An experimental investigation is conducted on a new adjustable thermoacoustically-driven thermoacoustic refrigerator (TADTAR). This refrigerator comprises of a thermoacoustic engine which drives a thermoacoustic refrigerator. This study aims to demonstrate the possibility to alter the TADTAR performance through the adjustment of specific ...

The Journal of the Acoustical Society of America, 2000
The world’s first completely solar powered, thermoacoustically driven, thermoacoustic refrigerator has been improved with increased cooling power and higher efficiency. A larger 24-in.-diam Fresnel lens provides increased heat power to focus sunlight at 550<th>°C onto the hot end of a 1-in.
