Thermal-Structural Characteristics of Multi-Layer Vacuum-Insulated Pipe for the Transfer of Cryogenic Liquid Hydrogen

As the world’s hydrocarbon supplies are gradually being depleted, search for alternative energy sources with acceptably low emissions of environmentally harmful pollutants is a growing concern. Hydrogen has been proposed by numerous researchers as fuel source ships. Liquid hydrogen (LH2) shown to be particularly attractive ship respect its ability reduce pollution, density, high performance in engines, and caloric value per unit mass. However, working liquid phase requires very (i.e., cryogenic) temperatures. The design cryogenic LH2 pipeline different from normal fluid pipe due change between gas states involved effect thermal structural characteristics on temperature during transportation through transfer pipeline. This study investigated material thermal-structural multi-layer vacuum-insulated system experiments finite element analysis. experimental numerical results can used database parameters analysis when designing applications such systems carriers hydrogen-fuelled
