Effects of surface viscosities on the motion of a droplet enclosing a translating particle
Ali Gürbüz, Hervé Nganguia, Guangpu Zhu +3
We investigate the influence of interfacial rheology on the motion of a compound particle consisting of a viscous droplet enclosing a translating rigid particle in the Stokes flow…
Self-propulsion of an elliptic phoretic disk emitting solute uniformly
Guangpu Zhu, Lailai Zhu
Self-propulsion of chemically active droplet and phoretic disk has been widely studied; however, most research overlooks the influence of disk shape on swimming dynamics. Inspired…
Viscoelastic levitation
Yunxing Su, Alfonso Castillo, On Shun Pak +2
The effects of viscoelasticity have been shown to manifest themselves via symmetry breaking. In this investigation, we show a novel phenomenon that arises from this idea. We observ…
Optimising low-Reynolds-number predation via optimal control and reinforcement learning
Guangpu Zhu, Wen. -Zhen Fang, Lailai Zhu
We seek the best stroke sequences of a finite-size swimming predator chasing a non-motile point or finite--size prey at low Reynolds number. We use optimal control to seek the glob…
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…
Film thickness distribution in gravity-driven pancake-shaped droplets rising in a Hele-Shaw cell
Isha Shukla, Nicolas Kofman, Gioele Balestra +2
We study here experimentally, numerically and using a lubrication approach; the shape, velocity and lubrication film thickness distribution of a droplet rising in a vertical Hele-S…
