A quantitative comparison of the usual and recent numerical treatments which are applied to the Smoothed Particle Hydrodynamics (SPH) method are presented together with a new free-surface treatment. A series of numerical treatments are studied to refine the numerical procedures of the SPH method particularly for violent flows with a free surface. Two dimensional dam-break and sway-sloshing prob...

In this study, the two-dimensional sloshing of water in a stepped based tank partially filled was analyzed using an arbitrary Lagrangian–Eulerian adaptive fixed-mesh method and including Smagorinsky turbulence model. The numerical model is verified by contrasting predictions made with experimental results. subjected to controlled one-directional motion imposed shake table. free surface evolutio...

A disastrous tsunami is generally known as the ocean water response to an offshore fault rupture consequence of a submarine earthquake. Such physical understanding, however, cannot explain generation 2018 Sulawesi earthquake induced Palu Bay tsunami. In this study, it demonstrated that sloshing effect dominates event if occurs in semi-closed body near epicenter and ground motion triggered by st...

Abstract Shallow-water sloshing motions in a three-dimensional rectangular tank are investigated. The Boussinesq-type equations terms of velocity potential and the finite-difference scheme applied for solutions numerical model. Through linking rate decay wave amplitudes to energy dissipation due friction at walls, linear damping term is proposed added into free surface boundary condition. Takin...

In this study, the liquid sloshing in a cylindrical tank considering soil–structure interaction and undergoing horizontal excitation is investigated analytically. Multiple rigid annular baffles are positioned on wall to mitigate sloshing. Firstly, combined with subdomain partition method for sloshing, complex domain partitioned into simple subdomains single condition boundary. Based continuity ...

The large-amplitude sloshing behavior of liquid hydrogen in a tank for heavy-duty trucks may have adverse effects on the safety and stability driving. With successful application field new energy vehicles, coupled thermodynamic performance during becomes more attractive. In this paper, three-dimensional numerical model is established to simulate coupling characteristics horizontal trucks. calcu...
