“…Relatively little work has considered such an approach for civil aircraft, with preliminary studies focused on numerical investigations on integration of fuel sloshing in aeroelastic models [8]. The use of smoothed particle hydrodynamics (SPH) and equivalent mechanical model (EMM) methods in fluid sloshing and fluid-structure interaction research is well established [41]. With the advent of high-performance computing, the use of detailed high fidelity SPH-based models for fluid sloshing problems is an attractive option.…”

“…Such a situation is caused by a reduction in hydraulic friction resulting from a further expansion of the hose due to the increased working pressure. The working pressure is higher because, when only the pumping station load is used to determine the location of pumping stations, the action of the inlet pressure head is taken into account after the hoseline is put into operation [9] .…”

To ensure a reasonable and cost-effective design pressure for the new composite polyurethane (PU) oil transfer hose, this study presents a mathematical model and hydraulic friction calculation formulas that account for variations in hydraulic friction resulting from the decrease in the elastic modulus. The hydraulic grade line of the PU hose exhibits a nonlinear equation with continuous curvature changes. To address this, we investigate a specific mathematical description method and employ numerical calculation methods to computerize the graphical calculation process. Additionally, the study examines the new pressure energy balance relationship in various transportation scenarios, such as fluctuating flow rates and cross-station transport, laying the groundwork for optimizing the operation plan.

Fluid sloshing within containers subjected to external motion is a crucial yet intricate phenomenon with implications across various industries. This study investigates sloshing in a rectangular liquid tank through a series of experiments examining pitch excitations with diverse excitation frequencies and amplitudes across different liquid carrying rates. By analyzing pressure data and imagery of the free liquid surface, statistical trends in peak pressure at measurement points within the tank are identified, revealing the nonlinear behavior of the fluid. Spectral analysis generates power spectrum curves that delineate frequency components and energy distribution within the sloshing dynamics. Key findings include the identification of resonance-induced violent sloshing at a 20% liquid-carrying rate and a resonant frequency shift at a 70% liquid-carrying rate due to nonlinearity, displaying a “soft spring” characteristic in the frequency response. The free liquid surface exhibits four distinct waveforms depending on frequency. Notably, at a 70% liquid-carrying rate and resonant frequency excitation, three-dimensional vortex waves emerge, highlighting a complex three-dimensional effect within the tank. The power spectrum shows that the dominant response frequency aligns with the excitation frequency and its multiples. This investigation enhances our understanding of the intricate nature of sloshing in various liquid-carrying conditions, offering insights valuable for diverse industrial applications.
