A multilayer model for multiscale flows of thin (and not-so-thin) films

If you have a question about this talk, please contact Catherine Pearson .

We recently proposed a model able to describe both “thin films” and “thick films” [1] both in the context of large-scale geophysical flows and down to lubrication scales . In this presentation, I will give an overview of the principal properties of this multilayer, semi-discrete approximation of the incompressible Navier–Stokes equations with a free-surface and its theoretical and practical connections with previous classical film models.
