Description
Cryogenic expanders are complex and expensive components in recuperative-cycle cryocoolers. To simplify cryogenic expander technology, we propose a novel acoustic expander. The acoustic expander utilizes sound waves in the expansion process without the need for complex moving parts at low-temperature; in contrast to turbine or piston expanders that require spinning shafts or moving displacers at low-temperature. This work models the operation of the acoustic expander and presents preliminary experiments that verify its function.
