Excerpt from Analytical Model for the Refrigeration Power of the Orifice Pulse Tube Refrigerator The general goal of this study is to gain a better understanding of the refrigeration mechanism and the capability of the ptr. More Specifically, this work is concerned with developing an analytical model for the refrigeration power generated in an orifice pulse tube refrigerator (cftr). With the aid of several simplifying assumptions, we derive equations which identify the important parameters in the system. Once the analytical expressions are devised, verification of the model is accomplished by comparing results to previous experimental studies as well as to experiments completed in this work. A simple, analytical model of the cooling power is useful for three reasons. First, such a model provides insight into the refrigeration mechanism. Often when a numerical model is used to rigorously describe a system, it is difficult to see the physics involved in the process. With an analytical expression, important parameters that affect performance are more easily recognized. Second, basic trends or dependencies of performance can be determined. Such dependencies will aid in optimization and indicate the range of parameters which should be studied in more detail either numerically or experimentally. Third, a simple analytical model will be useful for design. Although not as accurate as a numerical analysis, the model will be convenient for making approximate predictions of system size and refrigeration capacity of the ptr.

The last two years have witnessed a continuation in the breakthrough shift toward pulse tube cryocoolers for long-life, high-reliability cryocooler applications. New this year are papers de scribing the development of very large pulse tube cryocoolers to provide up to 1500 watts of cooling for industrial applications such as cooling the superconducting magnets of Mag-lev trains, coolmg superconducting cables for the power mdustry, and liquefymg natural gas. Pulse tube coolers can be driven by several competing compressor technologies. One class of pulse tube coolers is referred to as "Stirling type" because they are based on the linear Oxford Stirling-cooler type compressor; these generally provide coolmg m the 30 to 100 K temperature range and operate ^t frequencies from 30 to 60 Hz. A second type of pulse tube cooler is the so-called "Gifford-McMahon type. " Pulse tube coolers of this type use a G-M type compressor and lower frequency operation (~1 Hz) to achieve temperatures in the 2 to 10 K temperature range. The third type of pulse tube cooler is driven by a thermoacoustic oscillator, a heat engine that functions well in remote environments where electricity is not readily available. All three types are described, and in total, nearly half of this proceedings covers new developments in the pulse tube arena. Complementing the work on low-temperature pulse tube and Gifford-McMahon cryocoolers is substantial continued progress on rare earth regenerator materials.

This final report summarizes and presents the analytical and experimental progress in the present effort. The principal objective of this effort was the demonstration of a 0.25 Watt, 80 Kelvin orifice pulse tube refrigerator. The experimental apparatus is described. The design of a partially optimized pulse tube refrigerator is included. The refrigerator demonstrates an ultimate temperature of 77 K, has a projected cooling power of 0.18 Watts at 80 K, and has a measured cooling power of 1 Watt at 97 K, with an electrical efficiency of 250 Watts/Watt, much better than previous pulse tube refrigerators. A model of the pulse tube refrigerator that provides estimates of pressure ratio and mass flow within the pulse tube refrigerator, based on component physical characteristics is included. A model of a pulse tube operation based on generalized analysis which is adequate to support local optimization of existing designs is included. A model of regenerator performance based on an analogy to counterflow heat exchangers is included. Hendricks, John B. Unspecified Center...
