"Multi-component Lattice Boltzmann Simulations with Particle-Interface Interactions"
The presence of solid particles can play an important role in many multiphase/multi-component flows. Particles in the interface of an emulsion can stabilize it, preventing breakup. In this talk, I will discuss the extension of an existing free energy-based multi-component Lattice Boltzmann Method (LBM) to handle the transport of immersed solid particles of a finite size. The LBM uses a diffuse interface approach to model the interaction between different fluid components, and there is a two-way coupling between the particle and fluid motion. The force on a particle is computed by Momentum Exchange (ME), an algorithm unique to the LBM. However, a supplemental term must be introduced to account for the force of the interface on the particle. I will present a validation for the inclusion of this forcing term, and demonstrate the capability of the code by discussing simulations of drop impact with immersed solid particles and the rupture of a liquid bridge containing particles.
