A dynamic experimental apparatus was designed and constructed to investigate oscillating flow characteristics in a regenerator subjected to a periodically reversing flow established by means of a self-made linear compressor. Detailed experimental data of oscillating pressure drops and phase shift ch

โฆ Synopsis
In this work some experimental results obtained on a single stage Gifford McMahon cryocooler developed at the Officine Galileo for ir thermal vision applications are presented. The difference in thermodynamic behaviour of three ordinary and easy to find meshed nets used in our cryocoolers as a matrix for the thermal regenerator has been checked. The method used to detect the regenerator performance is indirect but very simple to put into practice and useful for an overall evaluation. A clear indication for the choice of the regenerator material comes from the experimental data.

In closed-cycle refrigerators the regenerators are the most critical components in determining the performance of the entire system: designing a regenerator with high effectiveness is thus of great importance in order to construct a good cryogenerator. For this reason seven series of measurements on

This work focuses on evaluation of the performance of a monolithic, versus standard packed bed, second stage regenerator in a Gifford-McMahon cryocooler. The monolithic, or bonded regenerator bed is made by means of a low temperature epoxy bonding technique developed [Adv. Cryog. Eng. 43B (1998) 159
