“…An improvement to the VOF model, presented as the cut-cell approach is described in [16]; according to the authors, it allows resolving the thin boundary layers along the curved walls for more accurate simulation of turbulent flows. Another approach to the free-surface representation based on JT-cells is presented in [21]. Here, the region of the flow is divided into three groups of cells: completely filled by fluid; partially filled or surface cells; and empty cells.…”

“…Destruction of these tanks by seismic action or shockwaves from a nearby explosion can lead to environmental catastrophe. So seismic design of liquid storage tanks requires the knowledge of sloshing frequencies and the hydrodynamic pressure on the walls [1]. Complex experimental investigation of loading processes is difficult and sometimes impossible for various reasons.…”

This paper deals with the fluid-structure interaction analysis of a shell partially filled with a liquid. The shell is considered to be thin and the Kirghoff-Lave linear theory hypotheses are applied. The liquid is ideal and incompressible. The problem of analysing the dynamics of shells of revolution partially filled with an ideal incompressible liquid was reduced to solving the system of singular integral equations. The solution was obtained by using a coupled BEM and FEM in-house solver. The tank structure is modelled by the FEM and the liquid sloshing in the fluid domain is described by the BEM. The shell vibrations coupled with liquid sloshing under the force of gravity were considered. The shell and sloshing modes were analysed simultaneously. The free vibration analysis of the elastic cylindrical shell was carried out using the proposed techniques. Keywords: fluid-structure interaction, liquid sloshing, free vibrations, boundary and finite element methods, systems of singular integral equations.

“…In their numerical model, the second-order accurate volume-of-fluid method is used to track the distorted and broken free surface. Popov et al [11] investigated the effect of acceleration and curvature on the fluid motion in rectangular containers and observed that the most intense sloshing occurs when the fill level is approximately 30-60%.…”

Abstract. This paper presents the free surface behaviour of liquid in a partially filled automotive fuel tank under uniformly accelerated motion. The liquid in the fuel tank is subjected to violent sloshing during sudden acceleration or stopping of the vehicle which will produce structural vibration and noise in the passenger compartment. To reduce this sloshing, baffles are used inside the tank. The objective of this work is to study the influence of vertical baffles and fill levels on free surface elevation of liquid in a partially filled fuel tank. The simulation of liquid free surface behaviour under uniform acceleration is done using ANSYS-FLUENT software. A numerical model is developed based on Volume of Fluid (VOF) technique to track the free surface motion of liquid. The explicit time discretization scheme is employed to solve the volume fraction equation. From the numerical analysis, amplitude of free surface elevation and slope of free surface are predicted. Experiments are carried out with transparent fuel tank, fabricated using glass fibre and epoxy resin. A uniform acceleration is applied to the tank and free surface displacements of liquid are captured using high speed camera. Also, an analytical model is formulated to find position of the free surface of liquid in a rectangular container subjected to uniform acceleration. The free surface profiles obtained from the simulations are compared with the experimental results.
