... ABSTRACT In the context of on board cryogenic liquid hydrogen containment system design, this paper describes the first achievements of a progressive model development for capturing all physical phenomena involved in the near wall region of the tank during severe sloshing. This paper...

... ABSTRACT A highly effective insulation system is essential for cryogenic liquefied gas fuel storage tanks, particularly for liquefied hydrogen (LH 2 ) with a boiling point of 20K (-253°C), much lower than other liquefied gas fuels like ammonia and natural gas. Unlike other fuels, advanced...

... ABSTRACT This paper presents a feasibility of numerical analysis aimed at investigating gas replacement operations within LNG cargo tanks. Preceding LNG loading, essential procedures including inerting, gassing-up, and cool-down are conducted to prevent explosions, enhance re-liquefaction...

... ABSTRACT Many existing studies show that the ocean tidal turbine experiences frequent and large-scale fluctuations of hydrodynamic loads during its operation, especially when effected by surface waves, which may lead to blade damage due to fatigue. Therefore, the physical wave tank...

... Spartype FOWTs have been installed in Japan as documented by ABS (2021) and reported by the news media (Offshorewind.biz, 2022). Preliminary studies and wave tank model tests were conducted by Duan, Hu and Wang (2015, 2016) to investigate the hydrodynamic responses of a 5 MW single-column classic Spar-type...

... involves describing the wave shape and kinematics at the point at which a wave breaks. Waves have been measured for decades both in the laboratory, as well as in coastal and open sea environments. In wave tanks and flumes, the surface elevation is typically measured at a single point using one capacitance...

... ABSTRACT The density stratification of seawater leads to the generation of internal wave wakes as a submerged body moves, and the characteristics of these wakes are closely related to the navigation speed of the submerged body. In this study, a wide-field density-stratified wave tank was used...
