SUMMARY:Symmetry breaking in fluid-structure interaction systems - Profess

DESCRIPTION:Two simple systems are analysed numerically: the flow past a c
 ylinder and that in a channel driven by a sinusoidal pressure gradient.  I
 n both\nconfigurations an elastic filament is present\, symmetrically plac
 ed and\nhinged at the wall (of the cylinder or the channel). In both cases
  we find\nthat a symmetry breaking bifurcation may arise through the fluid
 -structure interaction\, causing either a net lift (in the case of the cyl
 inder) or a net mean flow (in the pulsating channel). We explore some poss
 ible reasons for this behaviour.
