Abstract
Small, modular, efficient hydrogen liquefiers are needed to expand use of hydrogen as an energy currency. The Heisenberg Vortex Tube (HVT) is a novel cooling concept based on the Ranque-Hilsch Vortex Tube (RHVT) with a catalytic liner - the first concept to reverse the exothermic ortho-parahydrogen conversion to directly aid primary hydrogen cooling. The development of a vortex tube suitable for cryogenic hydrogen has never been attempted. Furthermore, the creation of a vorticial reactor for catalyzing hydrogen spin isomers has not been created. This thesis shows how such a cryogenic hydrogen vortex tube can be made and integrated with a vorticial reactor to create the HVT. Analysis of the design parameters of the HVT and experiment are presented. Initial experimental measurements of this new device are presented of hydrogen at conditions near 77 K, pressure ratio of 1.9, and cold fraction of 0.38.
