Experimental study and analysis of a thermoacoustically driven thermoacoustic refrigerator

Sādhanā, 2020
Experimental 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).

Design of thermoacoustic refrigerators

Cryogenics, 2002
in this paper the design of thermoacoustic refrigerators. using the linear thermoacoustic theory, is described. Due to the large number of parameters, a choice of some parameters along with dimensionless independent variables will be introduced. The design strategy described in this paper is a guide for the design and development of thermoacoustic ...

Improvements in an experimental thermoacoustically driven thermoacoustic refrigerator

The Journal of the Acoustical Society of America, 1997
A 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, 2002
The 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, 2000
Condensation 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, 2000
A 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, 2010
Thermoacoustic 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 ...

Thermoacoustic engines and refrigerators

AIP Conference Proceedings, 2012
Thermoacoustic engines and refrigerators use gas inertia and compressibility to eliminate many of the mechanical contrivances required by traditional engines and refrigerators while providing potentially attractive options that might reduce environmental impacts.
