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…
Effective longitudinal slip over grooves encapsulated by a nearly inviscid lubricant
Ory Schnitzer, Ehud Yariv
We calculate the effective slip length for a rectangularly grooved periodic surface encapsulated (i.e., fully wetted) by a lubricant fluid and subjected to exterior shear flow para…
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…
