Dynamic wetting boundary condition for continuum hydrodynamics with multi-component lattice Boltzmann equation simulation method

We present methodological innovations to the multicomponent lattice Boltzmann equation simulation method of Lishchuk, Care and Halliday (2003, Phys. Rev. E, 67, 036701) which allow for the simulation of dynamic contact lines (DCLs) in the continuum approximation. The scope of the improvements is demonstrated by examples validated by quantitative results. Our innovations allow the simulator access to an expanded range of simulation parameters like viscosity, viscosity contrast and interfacial tensions, and to obtain data with low levels of interfacial micro-current activity, in the region of the DCL.
