Forced Imbibition in Stratified Porous Media
Nancy B. Lu, Amir A. Pahlavan, Christopher A. Browne +3
Imbibition plays a central role in diverse energy, environmental, and industrial processes. In many cases, the medium has multiple parallel strata of different permeabilities; howe…

Particle motion nearby rough surfaces
Christina Kurzthaler, Lailai Zhu, Amir A. Pahlavan +1
We study the hydrodynamic coupling between particles and solid, rough boundaries characterized by random surface textures. Using the Lorentz reciprocal theorem, we derive analytica…

Three-dimensional pattern formation in suspensions of swimming micro-organisms
David Saintillan, Amir Alizadeh Pahlavan
Suspensions of self-propelled particles, such as swimming micro-organisms, are known to undergo complex dynamics as a result of hydrodynamic interactions. This fluid dynamics video…
