SUMMARY:The micro-fluid mechanics of synthetic swimming - Dr Eric Lauga\, 
 DAMTP\, Cambridge

CONTACT:Ms Helen Gardner
DESCRIPTION:A number of microorganisms are able to self-propel in a fluid\
 , including many bacteria\, spermatozoa\, ciliates\, and plankton. Inspire
 d by the biological world\, the engineering community been very active in 
 designing and implementing synthetic swimming strategies. In this talk we 
 will start by an introduction to the micro-fluid mechanics of such small-s
 cale swimming. We will then introduce three specific propulsion methods an
 d outline some of the research questions they generate: (1) Swimming by ro
 tating a rigid helix using an external field\; (2) Chemical locomotion via
  self-diffusiophoresis\; and (3) Exploiting standing acoustic waves to tra
 nsport rigid particles. We will finish by presenting a way to take advanta
 ge of swimming in order to perform rheological measurements.
