*Nucleation processes in fluids: cavitation, boiling, condensation, and
coupling with the macroscale*

*Prof. Carlomassimo Casciola, ERC ADVANCED*
UniversitÃ  La Sapienza

Nucleation of a second phase in a mother fluid is a ubiquitous phenomenon
whose prediction proved a formidable task, particularly in the case of
water. Phase transformations are part of our everyday experience, when
boiling water to prepare tea or coffee, or for windows to fog up on cold
and humid days. They are very complex processes that originate at the
molecular scale, where the incessant thermal agitation produces density
fluctuations [1]. The computations are based on a Ginzburg-Landau model
which, as only inputs, requires a reliable equation of state for the bulk
free energy and the interfacial tension of the water-vapor system. Rare
event techniques borrowed from statistical mechanics allow the
determination of the free-energy barrier and the nucleation rate. By
consistently including thermal fluctuations [2] in the spirit of
Fluctuating Hydrodynamics, the approach is extended to dynamic conditions
in the presence of solid walls of different wettability [3] to allow
coupling with fluid motion [4]. The talk will discuss a wide range of
phenomenologies, such as homogeneous and heterogeneous cavitation, nucleate
boiling [5], dropwise condensation, coupling with fluid flow, see figure,,
and a few exemplary applications highlighting collective effects that may
arise from the interaction of the nucleated phase with the mother fluid.
