# The Cahn-Hilliard equation: phase separation and interfaces

#### The Cahn-Hilliard equation: phase separation and interfaces

- Event time: 11:30am
- Event date: 20th May 2015
- Speaker: Giulio De Magistris (Formerly School of Physics & Astronomy, University of Edinburgh)
- Location: Room 2511, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

I will briefly introduce the Cahn-Hilliard equation and derive some well known results for the properties of the interface between two coexisting phases. I will then discuss some coarsening process in the phase separation. Finally, if there is any time left, I will try to discuss the case of a biphasic fluid, and its different coarsening scaling regimes.

If time and media supports allow, there will be some videos of some numerical simulations showing some coarsening process/some interfaces.
