I am a Ph.D. student in the Department of Civil and Environmental Engineering. Interfacial tension dominated flows and applied mathematics are two fields that keep me a happy and hungry student.

Multiphase Flow in Porous Media

Many natural and engineered processes involve one fluid displacing another in porous media. However, a full understanding of how porous material properties, such as wettability, influence the formation of patterns (and thus the efficiency of such displacement) has not yet been established. We aim to fill this gap through theoretical modeling and experiments.

Quasistatic fluid-fluid displacement in porous media: Invasion-percolation through a wetting transition

We first developed a model that, through pore-scale displacement mechanisms, captures the fluid-fluid front patterns in a quasi-steady regime. As the porous media wettability changes from strong drainage to strong imbibition, the model naturally crosses over from invasion-percolation to cooperative filling and corner flow (a mechanism that has eluded many of the models until now).

Signatures of fluid–fluid displacement in porous media: wettability, patterns and pressures

We then extended our fluid-fluid displacement model to arbitrary capillary numbers through analogy with an electric circuit, where resistors captured viscous effects while a combination of a capacitor and a battery reproduced the behavior of a meniscus in a pore throat. This allowed examining the signatures of the fluid-fluid displacement regimes (viscosity or capillary dominated) through both macroscopic displacement patterns and injection pressure signal alone. The latter is of particular importance since the pressure signal is often the only source of information in natural porous materials.

Comprehensive comparison of pore-scale models for multiphase flow in porous media

We then perform an objective comparison of a variety of state-of-the-art pore-scale models, including lattice Boltzmann, stochastic rotation dynamics, volume-of-fluid, level-set, phase-field, and pore-network models. We compare the results of the 14 participating teams both qualitatively and quantitatively using several standard metrics, such as fractal dimension, finger width, and displacement efficiency. We find that no single method excels across all conditions and that thin films and corner flow present substantial modeling and computational challenges.

Interfacial Fluid Dynamics

The dynamics of fluid-fluid interfaces has direct relevance to many industrial and manufacturing applications, such as printing, coating, detergency, oil recovery, and mineral processing. Yet, this field is abundant in unsolved fundamental problems. We aim to uncover the physical mechanisms at play in wetting dynamics and free-boundary problems with theory and experiments.

Characterizing dissipation in fluid–fluid displacement using constant-rate spontaneous imbibition

When one fluid displaces another in a confined environment, some energy is dissipated in the fluid bulk and the rest is dissipated near the contact line. Here we study the relative strengths of these two sources of dissipation with a novel experimental setup: constant-rate spontaneous imbibition experiments, achieved by introducing a viscous oil slug in front of the invading fluid inside a capillary tube. We show that a large fraction of dissipation takes place near the contact line, and rationalize the observations by means of a theoretical analysis of the dynamic contact angles of the front and back menisci of the oil slug—a result that bears important implications for macroscopic descriptions of multiphase flows in microfluidic systems and porous media.

Spin coating of capillary tubes

We present the results of a combined experimental and theoretical study of the spin-coating of the inner surface of capillary tubes with viscous liquids, and the modified Rayleigh-Plateau instability that arises when the spinning stops. We show that during the spin-coating, the thinning of the film is governed by the balance of viscous and centrifugal forces, resulting in the film thickness scaling as h ~ t^{-1/2}. We demonstrate that the method enables one to reach uniform micrometer-scale films on the tube walls. Finally, we discuss potential applications with curable polymers that enable precise control of film geometry and wettability.
