Mesoscale modelling of multiphase flow in contact with elastic surfaces

Abstract eng:
Coupling wetting and elasticity is of fundamental importance to the physics of wetting in general. It also plays an increasingly relevant role in many technological applications. One such potential application involves particles at interfaces, where the softness enhances their stabilising effects on emulsions. Here we present a novel simulation approach where the fluid phases are simulated adopting a freeenergy lattice-Boltzmann method [1], while the deformable elastic structure is modelled with a finite element representation. The coupling between the solid and fluid dynamics is handled through an immersed boundary method [2]. The approach is validated by simulating the statics and dynamics of soft particles at liquid-liquid interfaces.
