Until now there has been no agreed approach to the thermodynamic design of either type. In particular, the choice of regenerator packing has remained a matter for time–consuming and thus expensive trial–and–error development. There has been no way of knowing whether an existing fully developed unit is performing to the limit of its thermodynamic potential.
Stirling and Pulse–tube Cryo–coolers addresses these problems.
- An ideal cycle for the pulse–tube yielding heat, mass–flow and work;
- Previously unseen phenomena of real gas behaviour;
- Pictorial reliefs of pressure wave interactions;
- Multiple wave reflections in graphic perspective
- First solution of the regenerator problem by a full, unsteady gas dynamics treatment;
- First ever depiction of pulse–tube boundary–layer events (heat conduction, streaming ) driven by interacting left–and right–running pressure waves
- First analysis of the graded regenerator and optimisation of gas path design;
- Embryonic cook–book method of ab initio cooler design based on dynamic similarity and thermodynamic scaling.
Stirling and Pulse–tube Cryo–coolers raises the threshold from which first–principles design of regenerative cryo–coolers may start. Those wishing to extend their study of the subject beyond the well–trodden, ideal gas/quasi–steady–state rationalisations will require this book.
