Study of a thermo acoustic Stirling cooler
نویسنده
چکیده
A thermoacoustic-stirling cooler is built and performance measurements are performed. The cooler uses the acoustic power produced by a linear motor to pump heat through a regenerator from a cold heat exchanger to an ambient one. The cooler incorporates a compact acoustic network to create the traveling-wave phasing necessary to operate in a Stirling cycle. The network has a coaxial topology instead of the toroidal one usually used. The design, construction and performance measurements of the cooler are presented. A measured coefficient of performance relative to Carnot of 25% and a low temperature of -54°C are achieved by the cooler. This efficiency surpasses the performance of the most efficient standing wave cooler by almost a factor of two.

Sensitivity analysis of dependency of working fluid thermo-dynamics properties to temperature on performance of Gama-type Stirling engine
This research proposes the effect of temperature variation in the Prandtl number on the power, the efficiency and the heat loss of the Gama-type Stirling engine. It should be noted that the Prandtl number included the viscosity, the thermal conductivity coefficient and the specific heat at constant pressures of the working fluid, which the temperature dependency of such first two thermo-dynamic...

Measurements were performed to characterize the performance of a Free Piston Stirling Cooler over a wide range of temperatures and heat lifts. The temperature range investigated was from –120°C to +5°C on the cold head side and from 30 to 60°C at the warm head, while heat lifts from 10 to 100W were evaluated. The publication discusses aspects of the experimental part of the investigation, inclu...
متن کاملExperimental studies of a thermoacoustic Stirling prime mover and its application to a cooler
An acoustic field spontaneously induced in a thermoacoustic prime mover consisting of a looped tube and resonator is determined through simultaneously measurements of pressure P and velocity U. A thermal efficiency of the thermoacoustic prime mover of this type has been reported to reach 30%. The measurements of the acoustic field in the present system revealed that a phase lead of U relative t...
متن کاملOptimization of the Loop in a Travelling- Wave Thermo-acoustic Engine
Introduction A number of experimental realizations of thermo-acoustic engines that use an acoustic loop to feed energy back to a regenerator have been reported, mostly of the Thermo-Acoustic Stirling Heat Engine (TASHE) type. An alternative configuration is the simple wavelength loop with the linear alternator in a short side-branch, but with close to travelling-wave phasing on both sides of it...
متن کاملA compact, continuous-wave terahertz source based on a quantum-cascade laser and a miniature cryocooler.
We report on the development of a compact, easy-to-use terahertz radiation source, which combines a quantum-cascade laser (QCL) operating at 3.1 THz with a compact, low-input-power Stirling cooler. The QCL, which is based on a two-miniband design, has been developed for high output and low electrical pump power. The amount of generated heat complies with the nominal cooling capacity of the Stir...
