Performance of Regenerators at Low Temperatures
Many modern devices developed to provide small amounts of refrigeration at low temperatures are based on refrigeration cycles involving regenerators, e.g., Stirling cycle (Köhler and Jonkers ); Gifford-McMahon cycle (Gilford and McMahon ), and the Kirk cycle (Dean and Daly ). An integral part of each cycle is a small regenerator which may be packed with a variety of materials. Granville et al.  and others have carried out experimental work with larger regenerators and found that the theories of Hausen , Tipler , Lubboch and Bower , and Schalkwijk  can be applied to larger regenerators, with certain reservations.
