“…The results for the different width collapse well on a master curve. In addition, the experimental results can be fit with the exponential behavior obtained in the equation (14). The exponential trend leads to a value of the plateau w/τ ∞ f = 1.6 ± 0.3 cm s −1 whereas the best fit suggests that the plateau has a value of w/τ ∞ f 3.1 cm s −1 .…”

Damping of liquid sloshing by foams

When a container is set in motion, the free surface of the liquid starts to oscillate or slosh. Such effects can be observed when a glass of water is handled carelessly and the fluid sloshes or even spills over the rims of the container. However, beer does not slosh as readily as water, which suggests that foam could be used to damp sloshing. In this work, we study experimentally the effect on sloshing of a liquid foam placed on top of a liquid bath. We generate a monodisperse two-dimensional liquid foam in a rectangular container and track the motion of the foam. The influence of the foam on the sloshing dynamics is experimentally characterized: only a few layers of bubbles are sufficient to significantly damp the oscillations. We rationalize our experimental findings with a model that describes the foam contribution to the damping coefficient through viscous dissipation on the walls of the container. Then we extend our study to confined three-dimensional liquid foam and observe that the behavior of 2D and confined 3D systems are very similar. Thus we conclude that only the bubbles close to the walls have a significant impact on the dissipation of energy. The possibility to damp liquid sloshing using foam is promising in numerous industrial applications such as the transport of liquefied gas in tankers or for propellants in rocket engines.

“…A pressure-based finite element technique has been developed to analyze the slosh dynamics of a partially filled rigid container with bottom-mounted submerged components by Mitra and Sinhamahapatra (2007). Maleki and Ziyaeifar (2008) investigated the potential of baffles (horizontal ring and vertical blade baffles) in increasing the hydrodynamic damping of sloshing in circular-cylindrical storage tanks. Cho et al (2002) presented the fluid-structure interaction problems of fluid-storage containers with baffle, a disc-type baffle with an inner hole, by the structural-acoustic finite element formulation.…”

“…The experimental investigation of sloshing processes is difficult and sometimes impossible for various reasons. So the basic approach for these problems is mathematical modelling with numerical methods [10][11][12][13][14]. The effect of size and location of baffle on sloshing frequencies has been reported only in several studies involving rectangular and a generic cross-section tank [4,9,11].…”

This paper presents an analysis of low-frequency liquid vibrations in rigid partially filled containers with baffles. The liquid is supposed to be an ideal and incompressible one and its flow is irrotational. A compound shell of revolution is considered as the container model. For evaluating the velocity potential the system of singular boundary integral equations has been obtained. The single-domain and multi-domain reduced boundary element methods have been used for its numerical solution. The numerical simulation is performed to validate the proposed method and to estimate the sloshing frequencies and modes of fluid-filled cylindrical shells with baffles in the forms of circular plates and truncated cones. Both axisymmetric and non-axisymmetric modes of liquid vibrations in baffled and un-baffled tanks have been considered. The proposed method makes it possible to determine a suitable place with a proper height for installing baffles in tanks by using the numerical experiment.
