Leidenfrost Dynamics — •David Quéré — ESPCI & Ecole polytechnique, Paris

We discuss the Leidenfrost phenomenon, and particularly focus on its dynamical aspects: how can liquids levitate on a hot solid? what are their particular shape and evolution? what is the friction of these liquid hovercrafts when they move? how do they behave on an irregular solid? is it possible to create a Leidenfrost situation without heat? We'll see that the absence of contact between a substrate and a liquid deeply modifies the usual laws of wetting.
