PHYSICAL MATHEMATICS SEMINAR
TOPIC: HOW FLEXIBLE BODIES INTERACT WITH FLOWING FLUIDS
SPEAKER: MICHAEL SHELLEY
Applied Mathematics Lab
Courant Institute, NYU
ABSTRACT:
The interaction of flowing fluids with compliant bodies gives rise to a
class of beautiful free-boundary problems that is central to many
scientific problems in biology and engineering. I will overview my work
on several fundamental examples: At the low Reynolds number end, I discuss
the modeling and simulation of the dynamics of elastic fibers, and focus
upon buckling instabilities driven by flow or growth processes. At the
high Reynolds end, I discuss recent experiments at Courant concerning the
interaction of both "flags" and "elastic plates" with high-speed flows.
For each, I will show how modeling, analysis, and computation sheds light
on the fundamental mechanisms underlaying the experimental results.
