Cryocoolers: the state of the art and recent developments.

چکیده

Cryocooler performance and reliability are continually improving. Consequently, they are more and more frequently implemented by physicists in their laboratory experiments or for commercial and space applications. The five kinds of cryocoolers most commonly used to provide cryogenic temperatures for various applications are the Joule-Thomson, Brayton, Stirling, Gifford-McMahon, and pulse tube cryocoolers. Many advances in all types have occurred in the past 20 years that have allowed all of them to be used for a wide variety of applications. The present state of the art and on-going developments of these cryocoolers are reviewed in this paper. In the past five years new research on these cryocoolers has offered the potential to significantly improve them and make them suitable for even more applications. The general trend of this new cryocooler research is also presented.

The existing health care systems focus on treating diseases rather than preventing them. Patients are generally not tested unless physiological symptoms are appeared. When they do get tested, the results often take several days and can be inconclusive if the disease is at an early stage. In order to facilitate the diagnostics process and make tests more readily available for patients, the conce...

Recent Advances in Hydraulic Fracturing for Enhanced Well Productivity: State of the Art Report

 Hydraulic fracturing of horizontal wells is considered as the main reason for the phenomenal increase in production of oil and gas from marginal and unconventional reservoirs in North America. The process evolution started more than a decade ago and has resulted in ultra-low permeability reservoirs producing at close to the same rates as some of the very prolific reservoirs in the Middle East,...

Spectral Estimation of Stationary Time Series: Recent Developments

Spectral analysis considers the problem of determining (the art of recovering) the spectral content (i.e., the distribution of power over frequency) of a stationary time series from a finite set of measurements, by means of either nonparametric or parametric techniques. This paper introduces the spectral analysis problem, motivates the definition of power spectral density functions, and reviews...

Cryocoolers for Microsatellite Military Applications

Space qualified cryocoolers have been extensively developed for large military and commercial satellite electro-optical (EO) infrared (IR) missions, but not so for microsatellites due to the complexity of the thermodynamics and fluid mechanics of the mechanical refrigeration system. The trend in military responsive space programs is leaning towards microsatellites that are cheaper and faster to...
