Details:The dynamics of thin liquid films will be discussed through 2 classical examples: (i) the Landau-Levich film and (ii) levitated Leidenfrost drops. In the first problem one considers the withdrawal of a solid object from a liquid reservoir, which leaves a thin film on the solid. We recently discovered film profiles that are completely different from the classical solution proposed by Landau and Levich in the 1940s. The second problem consists of evaporating drops that are levitated above a hot plate thanks to the so-called Leidefrost effect. Such a drop undergoes two types of instabilities, one of which will be explained in detail. | ||
