SPH modelling of dissipative sloshing flows under violent vertical harmonic excitation

Investigation on the sloshing effect in a 2D tank under harmonic excitation using Smoothed Particle Hydrodynamics (SPH) and Finite Volume method (FVM)

Abstract Sloshing describes liquids motion in the semi-filled tanks, and exerts dynamic loading on its walls. This effect is of great importance in a number of dynamic systems e.g. aerospace vehicles, road tankers, liquefied natural gas carriers, elevated water towers and petroleum cylindrical tanks. Pressures insert impacts which are important for structural strength evaluation and its co...

Multi-phase Modelling of Violent Hydrodynamics using SPH

SPH is a relatively new, rapidly evolving Lagrangian meshless method that is currently being applied in a large variety of cases, ranging from astrophysics to nuclear engineering. However, most of these cases have been treated so far as single phase cases, therefore limiting both the accuracy of the method and the range of cases that can be solved and importantly the physics captured. However, ...

A Boundary Element Investigation of Liquid Sloshing in Coupled Horizontal and Vertical Excitation

Sloshing flows in a two-dimensional rigid rectangular tank under specified excitations in the coupled horizontal and vertical modes are simulated by using a higher-order boundary element method BEM . The liquid sloshing is formulated as an initial-boundary-value problem based on the fully nonlinear potential flow theory. And a semi-mixed Eulerian-Lagrangian technique combined with the 4th-order...

Dissipative Particle Dynamics Modelling of Low Reynolds Number Incompressible Flows

A numerical investigation into the correction algorithms for SPH method in modeling violent free surface flows

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...
