The leading order terms in a curvature expansion of the surface tension, the Tolman length (first order), and rigidities (second order) have been shown to play an important role in the description of nucleation processes. This work presents general and rigorous expressions to compute these quantitie...

The gravity-driven spreading of one fluid in contact with another fluid is of key importance to a range of topics. These phenomena are commonly described by the two-layer shallow-water equations (SWE). When one layer is significantly deeper than the other, it is common to approximate the system with...

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...
