Universal square-root-log scaling for slender-body end effects
Gunnar Peng, Ory Schnitzer
The charge on a conducting cylinder becomes uniformly distributed at large aspect ratios, albeit very slowly and with nonuniformity persisting near the ends. We show that the charg…

Slip over liquid-infused gratings in the singular limit of a nearly inviscid lubricant
Gunnar G. Peng, Ehud Yariv, Ory Schnitzer
We consider shear-driven longitudinal flow of an exterior fluid over a periodic array of rectangular grooves filled with an immiscible interior fluid (the "lubricant"), the grooves…

Bistability and charge-density blowup in the onset of drop Quincke rotation
Gunnar G. Peng, Ory Schnitzer
Particles in a sufficiently strong electric field spontaneously rotate, provided that charge relaxation is slower in the particle than in the suspending fluid. It has long been kno…
