This book will explore all key mathematical methods that need to be learned in order to
model a cryocooler with all its various aspects and physical phenomena. The cryocooler
will be studied in terms of thermodynamics, harmonic approximations, nodal numerical
modelling, 2D and 3D modelling, and hydrodynamic modelling. Furthermore, data analysis
methods that employ more recently developed machine learning methods will be
explored that improve multi-parameter optimisation methods, and introductory analysis
methods for integrating cryocoolers into spacecraft systems will be presented.
