Résumé
Recently, Younes et al. (2022) developed a phase -field -based Lattice Boltzmann Method (LBM) model capable of capturing the merging of capillary bridges in a triplet configuration without relying on geometrical criteria, thus enabling an easy transition from pendular to funicular regimes. However, the computational time of the formation of capillary bridges is quite significant particularly when it comes to coupling a macroscopic method (e.g. FEM) with a DEM-LBM coupling model to simulate engineering structures. In this study, we present a parameter optimization strategy aimed at accelerating the computational efficiency of the LBM alone. We show that even by not accounting for transient evolutions, we can still accurately obtain capillary forces with an error margin limited to 5% at equilibrium.
