We present a mesoscopic model able to capture the physics of drops moving across patterned surfaces. In this model, interfaces appear naturally, and "both chemical and topological patterning ran be incorporated wit h relative ease, making it particularly suitable to study the behaviour of evolving drops. We summarise results on drop dynamics, including drops spreading on a chemically patterned...
The main purpose of this paper is to present a new method for the study of single fluid mixing in a stirred vessel. The simulation has been realized with a parallel implementation of the Lattice Boltzmann coloured particles model. The mixing phenomenon is compared with the one derived with a Lagrangian approach.
