DESCRIPTION:Deterministic lateral displacement (DLD) is a tech
 nique widely used in microfluidics for size-based 
 separation. DLD devices typically consists of an a
 rray of static micro-posts that deflect the motion
  of oncoming particles using steric repulsion. In 
 this project\, we expand the concept of DLD by sho
 wing that a system with a rotational and translati
 onal motion near a solid boundary can trap and tra
 nsport passive particles. Trapping is achieved bec
 ause free-flowing finite-size particles cannot fol
 low flow streamlines as a result of their collisio
 n with a solid boundary\, and thus have move later
 ally to into a flow vortex in which they are trapp
 ed. The trapping mechanism is explained analytical
 ly in two dimensions and investigated numerically 
 for rolling ellipsoids in three dimensions.
