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 globally …

Advances in microfabrication enable the tailoring of surfaces to achieve optimal sorting,
mixing, and focusing of complex particulate suspensions in microfluidic devices. Corrugated …

This study proposes a meticulous friction torque model considering both the asperity
interaction and fluid traction mechanisms in micro-scale physical analysis. The fractal theory …

In several phenomena in biology and industry, it is required to understand the
comprehensive behavior of sedimenting micro-particles in fluids. Here, we use the …

We study theoretically and experimentally pressure-driven flow between a flat wall and a
parallel corrugated wall, a design used widely in microfluidics for low-Reynolds-number …

Particle motion near non-plane surfaces can exhibit intricate hydrodynamics, making it an
attractive tool for manipulating particles in microfluidic devices. To understand the …

We generalize classical dispersion theory for a passive scalar to derive an asymptotic long-
time convection–diffusion equation for a solute suspended in a wide, structured channel and …

We explore hydrodynamic interactions between microswimmers and corrugated, or rough,
surfaces, as found often in biological systems and microfluidic devices. Using the Lorentz …

Geometric confinements play an important role in many physical and biological processes
and significantly affect the rheology and behavior of colloidal suspensions at low Reynolds …
