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).

Improvements in an experimental thermoacoustically driven thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 1997A thermoacoustically (heat) driven, thermoacoustic refrigerator apparatus, having a novel topology, has produced significant cooling power and efficiency. It has achieved a cooling temperature span of 60 °C, and 91 W of cooling power at a span of 25 °C, with an overall COP of 0.15. These numbers were produced with a porous carbon refrigerator stack and

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

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.

Design and construction of a solar-powdered, thermoacoustically driven, thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 2000A thermoacoustically driven thermoacoustic refrigerator powered by solar thermal energy has been successfully built and tested. A 0.457 m diameter Fresnel lens focuses sunlight onto the hot end of a 0.0254 m diameter reticulated vitreous carbon prime mover stack, heating it to 475 °C, thereby eliminating the need for the most troublesome component in a

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 ...

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 ...
