The phoenix of Leidenfrost

22 March 2021, 2.00 PM - 22 March 2021, 3.00 PM

Professor David Quéré (ESPCI Paris & École polytechnique)

These colloquia will take place at 14:00 (sharp) on Mondays (note time), online using zoom; link below abstract.

It has been reported in 1756 that a drop of a volatile liquid placed on a very hot plate does not boil, but instead levitates. Since its description by a German physician, Johann Leidenfrost, this phenomenon has generated many surprises, with recurrent resurgences from its ashes. We’ll discuss some of these resurgences, including the geometry of these objects; the possibility to control (or not) the elusive droplets; ways to tune the temperature at which the phenomenon occurs. We’ll illustrate our talk with short movies, the different phenomena at stake being rather visual, and, hopefully, adapted to an on-line talk.
