SPH and ALE formulations for sloshing tank analysis

Evaluation of Sloshing Load Acting on Fixed Roof of Liquid Storage Tank Based on Sph Simulation

It is difficult to evaluate the sloshing load acting on a fixed roof of tank because it depends on the collision of the liquid to the roof. In this paper, the SPH simulation was introduced to evaluate the load acting on a fixed roof. The results obtained by the simulation showed good agreement with those obtained from other method. In addition, the effect of the roof-liquid clearance on the slo...

Time-discrete higher order ALE formulations: a priori error analysis

We derive optimal a priori error estimates for discontinuous Galerkin (dG) time discrete schemes of any order applied to an advection-diffusion model defined on moving domains and written in the Arbitrary Lagrangian Eulerian (ALE) framework. Our estimates hold without any restrictions on the time steps for dG with exact integration or Reynolds’ quadrature. They involve a mild restriction on the...

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...
