Stabilization of liquid sloshing in the presence of foam using Lattice Boltzmann Modelling approach

The free surface of a glass of water which is moved periodically exhibits oscillatory motion with a high amplitude. The amplitude decreases significantly when a layer of foam is present on top. In this work we first experimentally study the effect of frequency and amplitude of motion on the deformation of the interface. We use a Lattice Boltzmann approach to describe the dynamics of the interface. The model based on a bottom up approach, i.e. Shan- Chen model is used to investigate the interface deformation. The role of the rheology of foam on the interface dynamics is studied using a diffuse interface model. The role of different rheological models of foam on the interface movement will be highlighted.
