SUMMARY:The Fluttering and Tumbling of Mobius Bands - George Fortune (Univ
 ersity of Cambridge)
DTSTART:20180309T130000Z

CONTACT:Anne Herrmann
DESCRIPTION:Ranging from the fluttering and tumbling of a maple seed to th
 e steady falling of a conker\, examples of solid objects falling in air at
  intermediate Reynolds numbers are everywhere in nature. The trajectories 
 are typically very complex due to the interplay between inertial and visco
 us effects.\nThis talk will focus on the motion of a Mobius band i.e. a su
 rface which when embedded in three dimensional Euclidean space has only on
 e side and one boundary. This body is very interesting to study due to the
  large range of different angles of attack present in the body. This leads
  to many different types of behaviour being observed.\nI introduce a fluid
  force model to describe the motion of the system. This is validated throu
 gh comparison of experimental results collected in the lab with numerical 
 solutions generated using the model. This allows us to characterise an int
 eresting array of different kinds of motion.
