Résumé
[en] The trend towards hydrogen technologies has recently gained weight in order to reduce fossil fuel CO2 emissions. On this path, Coexpair has developed an interest in hydrogen storage. \\
In this context, this master's thesis presents first the different types of pressure vessels available on the market to understand the benefits of the all-composite Type~V tanks. A literature review of the past and current use of hydrogen in the transport industry is conducted to identify the type of tank used for each dedicated transportation mean. \\
This report proposes a methodology for the preliminary design of a Type~V filament-wound pressure vessel to store gaseous hydrogen for a tugboat application. A complete analytical study is conducted to determine the optimal domes geometry and the winding angle evolution over them based on non-geodesic trajectories. The classical lamination theory is used to compute the thickness required in the pressure vessel parts and a recent formulation is employed to compute the thickness evolution in the domes considering fibers overlap. A finite element analysis is led for the cylindrical part of the vessel to highlight the limitations of the analytical study. The tank is compared to other designs present on the market through performance indices, showing that the proposed design presents an added value. \\
The last part of the report studies the sloshing inside a liquid hydrogen tank for a medium-range aircraft using the Particle Finite Element Method developed at the University of Liège. The results provided by the simulations are corroborated by an experimental test conducted with a test tank. The parameters used to conduct the simulations and their implication are highlighted. Free-surface evolution and pressure fluctuations are presented for horizontal and vertical sloshing in a full-size cylindrical tank.
