Xiaojing (Ruby) Fu

PhD Student

I am a PhD candidate in the department of Civil & Environmental Engineering at MIT. I obtained my MS in Computation Design & Optimization from MIT in 2015 and BS in Applied Mathematics & Statistics from Clarkson University (Potsdam, NY) in 2011.

My research theme is on modeling and simulation of multiphase and multicomponent flows in geophysical processes. My work is motivated by applications in carbon sequestration and natural gas hydrate systems.

Thermodynamic coarsening arrested by viscous fingering in partially miscible binary mixtures

snapshot of a binary mixture drive by viscous fingering under a left-to-right background flow

Video 1 (Ostwald ripening in two-component two-phase mixture)

This is a numerical simulation describing the process of nucleation and coarsening of gas bubbles (red) out of a liquid (pink) that is initially supersaturated.

Video 2 (Arrest of Ostwald ripening under viscous fingering)

This is a numerical simulation showing the dynamic interactions amongst gas bubbles (red) dispersed in a more viscous liquid (pink) when the mixture is driven under a cyclic background flow. The gas bubbles are first nucleated without background flow until t=40. Once flow is introduced at t=40, the gas-liquid displacement is destabilized by a viscosity contrast of 148.
