Lattice Boltzmann simulations of three-dimensional drops spreading on a uniform solid surface will be discussed. It will be shown that, if the liquid–liquid interface is sufficiently thick, the contact line velocities obtained from the simulations agree well with theoretical predictions based...

The results of a lattice Boltzmann simulation for collisions between two liquid drops in an immiscible liquid in a linear Stokes flow will be presented. The results will be compared with existing experimental results and asymptotic solutions. The mixing of a contaminant that is initially...
