  • A three-dimensional simulation study on the lateral capillary forces (LCFs) between two floating and immersion spherical particles was carried out, using a modeling approach introduced in the framework of Shan-Chen lattice Boltzmann model for multi-component fluids. Solid-fluid interactions and wetting property of a colloidal particle could be taken into account at the mesoscopic level using a simple manner. Results show good agreement with theoretical results, and the so called “1/L” theory is demonstrated. At the same time, the linear relationship between immersion LCF and fluid interfacial tension for fixed interparticle distance is well achieved. These demonstrate that the model is a promising tool for the simulation of phenomenon such as self-assemblies of colloidal particles.
