Abstract

In the present work a critical analysis about the liquefaction technology research for medium and small scale systems and transport ones is presented. In particular small scale liquefaction systems are investigated. The thermal-fluid dynamics of the liquid hydrogen flowing inside the transport pipelines is studied and the physical phenomena associated with fluid flow and conductive-convective heat transfer are discussed. Open issues such as external thermal load, boil-off and pumping power are discussed too.
