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…

Equatorial blowup and polar caps in drop electrohydrodynamics
Gunnar G. Peng, Rodolfo Brandao, Ehud Yariv +1
We illuminate effects of surface-charge convection intrinsic to leaky-dielectric electrohydrodynamics by analyzing the symmetric steady state of a circular drop in an external fiel…
