Published: 4/2/2007
Authors: V. Arp, Yonghua Huang, Ray Radebaugh, G.B. Chen
Abstract: We describe a new form of a fluid state equation, based on a conceptual extrapolation from the Debye equation for the specific heat of solid materials. The Debye characteristic temperature, theta, which is nominally a constant for solids, becomes a f ...

12. Measurement of Heat Conduction Through Bonded Regenerator Matrix Materials
Published: 12/1/2003
Authors: Michael A Lewis, Ray Radebaugh
Abstract: Regenerative heat exchangers have had a significant influence on the development of small refrigerators for cryogenic applications. The optimized design of these regenerators takes into account the axial thermal conduction of the matrix. Until rece ...

13. The Development and Application of Cryocoolers Since 1985
Published: 4/1/2003
Author: Ray Radebaugh
Abstract: Many significant new developments in cryocoolers have occurred since about 1985 that have lead to grealy improved efficiencies, lifetimes, compactness, and low temperature limits. Many of the improvements have been spurred by the requirements of sev ...

14. Refrigeration Methods for Superconductors
Published: 12/1/2002
Author: Ray Radebaugh
Abstract: This chapter reviews various methods commonly used for achieving the cryogenic temperatures required of superconducting materials. The problems associated with cryogenic refrigerators (cryocoolers), such as poor reliability, low efficiency, electrom ...
