Abstract Sloshing is relevant in several applications like ship tanks, space and automotive industry seiching harbours. Due to the relationship between sloshing motions possibility of structural damage, it important represent this phenomenon accurately. This paper investigates at shallow liquid depths a rectangular container using experiments RANS simulations. Free forced sloshing, with without...

The seismic analysis of ground-supported cylindrical steel tanks subjected to lateral harmonic displacement loadings has been carried out. This paper numerically evaluates the structural response various tank geometries due resonant sloshing. numerical investigation is performed using a two-way fluid interaction approach that couples computational dynamics with finite element transient analysis...

In this work, we present a new monolithic strategy for solving fluid–structure interaction problems involving incompressible fluids, within the context of the finite element method. This strategy, similar to the continuum dynamics, conserves certain properties, and thus provides a rational basis for the design of the time-stepping strategy; detailed proofs of the conservation of these propertie...

The elevated reinforced concrete tanks assessed in the current work were subject of a nonlinear sloshing analysis resulting from fluid–container interactions. primary response quantity interest was height free surface sloshing. To achieve this aim, effect liquid contents on seismic behavior subjected to various sets far- and near-fault ground motions measured. variables considered study include...

Sloshing is a common flow phenomenon in liquid cargo tanks and has great negative impact on the stability safety of ship navigation. It important to understand sloshing process under excitation complex external conditions for transportation cargo. In this paper, characteristics tank are studied combination roll surge. The pressure distribution at different positions discussed, along with influe...

This paper presents a numerical study of the free-surface evolution for inviscid, incompressible, irrotational, horizontally forced sloshing in a twodimensional rectangular vessel with an inhomogeneous bottom topography. The numerical scheme uses a time-dependent conformal mapping to map the physical fluid domain to a rectangle in the computational domain with a time-dependent aspect ratio Q(t)...

High-Reynolds-number asymptotics and numerical simulations are used to describe twodimensional, unsteady, pressure-driven flow in a finite-length channel, one wall of which contains a section of membrane under longitudinal tension. Asymptotic predictions of stability boundaries for small-amplitude, high-frequency, self-excited oscillations are derived in the limit of large membrane tension. The...

This paper presents a computational study of the fluid-structure interaction (FSI) mechanism in pressurized commodity tank cars in railroad application. Within the Lagrangian framework of Abaqus/Explicit, finite element analysis (FEA) is conducted to predict the structural response of tank cars under dynamic impact loading. A three-phase approach is adopted that explicitly models pressurized ga...

The severe sloshing induced by earthquake in cylindrical liquefied petroleum gas (LPG) storage tank is of great concern for liquid design. For suppressing sloshing, porous material attached to inner periphery the wall proposed and studied numerically using OpenFOAM. model was validated against with available data without ring baffle, flow through media a U-tube dam break. Fair agreements betwee...
