Abstract: 

This talk is the second part of our introduction to modeling phase transitions in fluids.
We start by motivating our study of methane hydrate, an ice-like substance containing molecules of gas. Next we overview our work on hydrate formation and dissociation models at the basin scale, and how we used data from various collaborations to build and validate these models.
Next we motivate and describe our phase-field model of methane hydrate at the pore-scale which draws from the work of Tegze, Granasy, Kvamme et al, on gas hydrates from 2004-2010. The main challenge is to handle multiple components that can exist in multiple phases, and to work with a model which involves enough realistic complexity, yet is amenable to some mathematical and numerical analysis.
