Drexel University Improves the Performance of a New Design of Cryocoolers

Energy & Power

Drexel University

While the application areas of cryocoolers are exciting, the underlying physics and computational tools required for simulating the systems are complex. The features available in ACE+ Suite allowed us to overcome the demands and develop realistic models for improving the performance of a novel design of cryocoolers.

Coupled flow and heat transport in the various components of a cryocooler is complex and unstable. Drexel research team had a challenge to study the work principles of a cryocooler and improve the product design while avoiding physical experiments. The simulation challenge included meshing a complicated geometry and solving complex system with moving boundaries and non-porous, porous zones.


Design an efficient and reliable cryocooler Reduce cost and production time by approximately 50% Improve performance of cryocooler and identified key parameters with simulation & sensitive analysis Generate high quality meshes reducing simulation time Benefit from great technical support provided by ESI’s engineers
