DESCRIPTION:Speaker: James Roggeveen (Harvard)\n\nTitle: Geometry-driven dr
 ift of passive particles in flows.\n\nAbstract:\n\nIn low-Reynolds-number 
 flows\, an active swimmer is required to develop non-reciprocal swimming s
 trategies to achieve sustained propulsion. However\, it is also possible f
 or passive particles to drift\, or move in directions different from the m
 ean background flow\, by virtue of their geometry and deformability. Motiv
 ated by a desire to understand the motion of elastic fibers in low-Reynold
 s-number flows\, I present a study of the conditions required for both rig
 id particles and simple elastic particles to drift and how that drift may 
 be tuned as functions of both the flow and the particle shape. In particul
 ar\, I will focus on a class of particles we call hinges\, which serve as 
 qualitative analogs for more general curved fibers and show that adding el
 asticity to these hinges leads to symmetry breaking in oscillating flows.
