Discussed are the link conditions which appeares in analyzing a multi-stage refrigerator or a Cooke-Yarborough engine employing a computer code THERMOACOUSTICA based on thermoacoustic theory. At a link point, intensive quantities such as temperature and pressure are common to all branches and flow quantities such as energy flow, work flow, heat flow and volume displacement of fluid are continuous. These link conditions are discussed in detail. The link conditions are general, since they are applicable to links which appear in thermoacoustic devices equipped with a displacer piston.
