abstract:
Small amounts of liquid deposited on a substrate are an everyday phenomenon. From a
theoretical point of view this represents a modelling challenge, due to the multiple scales
involved: from the molecular interactions among the three phases (solid substrate, liquid
film and surrounding vapor) to the hydrodynamic flows. An efficient way to deal with this
multiscale problem is the thin-film equation. Solving the thin film equation directly is a difficult task, because it is
a fourth order degenerate PDE. Swalbe.jl approaches this problem from
a different angle. Instead of directly solving the thin film equation we use a novel method based
on a class lattice Boltzmann models riginally developed to simulate
shallow water flows
