SUMMARY:Hydrodynamic modes of resuspension - Dr Stuart B. Dalziel\, GK Bat
 chelor Laboratory &amp\; DAMTP
DTSTART:20060602T100000Z
DTEND:20060602T110000Z
UID:TALK4958@talks.cam.ac.uk
CONTACT:Dr C. P.  Caulfield
DESCRIPTION:In many scenarios\, lifting relatively dense particles from a 
 sediment bed is far more difficult than might be anticipated from the conc
 entrations of small particles found in the atmosphere and marine environme
 nts. While the reasons for this difficulty are fairly well understood\, un
 til recently most studies of relatively fine dust particles in the atmosph
 eric context have concentrated on the ballistic collisions of saltating 's
 and' particles. This talk will explore some elements of fluid structure/pa
 rticle bed interactions\, with particular emphasis on the role of the wake
  behind other particles and the resuspension due to rain drops.\n
