This course will examine the basic theories and applications of cryogenic systems. We will have an overview of cryogenic system design and analysis techniques based on our general understanding of the fundamental principles of thermodynamics, fluid mechanics and heat transfer. Topics that will be covered are as follows; the components of cryogenic systems and their performance, the diverse examples of cryogenic systems, several cryogenic refrigeration systems, liquefaction systems, storage/tranfer systems, etc.
