We present a perturbation theory that combines the use of a third-order Barker–Henderson expansion of the Helmholtz energy with Miepotentials that include first- (Mie-FH1) and second-order (Mie-FH2) Feynman–Hibbs quantum corrections. The resulting equation of state, the statistical associating fluid...

For liquid hydrogen (LH2) to become a global, carbon-free energy commodity, scaling-up of liquefaction, storage and transport technologies requires extensive research and engineering. The present work analyses a large-scale LH2 transfer process from onshore storage to seaborne storage by dynamic sim...

Mathematical models that represent two heat exchanger technologies are developed and solved to compare their performances in the cryogenic part of the hydrogen liquefaction process. Key performance parameters such as volume, thermal match and hydrogen-conversion rate are discussed for heat exchanger...

A fiber optic interferometer based on core diameter mismatch is used in reflection mode to study the behavior of ethanol solutions with regards to concentration dependent thermal properties and phase transitions. A method to simultaneously measure both temperature and ethanol concentration in system...
