“Modeling of thermofluid processes in liquid hydrogen storage and transfer systems”

Hydrogen is a promising clean and renewable fuel that can help humanity impede the catastrophic climate change. However, to produce, store, and transport hydrogen in the energy-dense liquid form, low cryogenic temperatures are required, as hydrogen boils at about 20 K. Investigation and characterization of liquid hydrogen processes, components, and systems represent the main R&D directions of the Hydrogen Properties for Energy Research (HYPER) Center at Washington State University. In this talk, our efforts on modeling thermofluid phenomena involving cryogenic and liquid hydrogen will be presented. The employed modeling methods range from lumped-element models to high-fidelity computational fluid dynamics simulations. The discussed applications include dynamic processes in liquid hydrogen storage tanks, critical phase-changing flows, para-orthohydrogen conversion for cryocooling, Taconis oscillations that lead to large heat leaks into cryogenic tanks, multiphase flow instabilities important for transferring liquid hydrogen, and other unsteady phenomena. The developed models can help engineers optimize design and operations of liquid hydrogen systems with higher confidence.
