Cryogenics is mission-critical for several emerging applications, namely, quantum technologies, detectors on ground and space, sustainable aviation and many more. Lately, this low temperature science and technology is gaining traction in our daily lives. Take for example the role of cryogenics in vaccine production and transportation, providing oxygen to patients in a hospital, cryogenic liquids in food processing, liquid natural gas production, storage and transport, hydrogen as the emerging new fuel.
Designing cryogenic systems require multi-disciplinary knowledge, in particular thermal and material science. In this course, we will address temperature dependent properties of materials and provide training in the use of NIST-REFPROP fluid property database. Thermodynamic processes will be revisited and applied in the cryogenic component/system context. Since our environment is far from cryogenic temperature it is very important to master the kinetics of heat transfer between the ambient and the cryogenic environment. We will address, all three modes of heat transfer in this course and apply this knowledge to the design of cryogenic components and systems. Various types of closed cycle cryocoolers will be introduced and analyzed. A liquefier which is a system that converts gas to liquid will be introduced and a tour of our inhouse liquefier is planned. The basics of experimental techniques in cryogenics will be introduced that includes hardware demonstration in our research labs. A design assignment where you will be asked to develop a theoretical model of a heat exchanger will be part of the assessment. An industrial guest with a cryogenics background will introduce applied concepts.
