Miniature Joule-Thomson cryocooling: theory and practice

The principles behind Joule-Thomson cryocooling provide a demonstration of real gas thermodynamics. For those with interest in thermodynamics and cryocooling, these ideas will be compelling and inspiring. The Joule-Thomson effect and cryocooling completely rest upon the extent of real gas deviating from the ideal one. The book provides a wide coverage of the important subject and gives a systematic and clear presentation which facilitates auto deduction. The book is presented in clear language to help the reader develop a full understanding of the Joule- Thomson cryocooler.
