Description
In the world of moderate Reynolds number, everyday turbulence of fluids
flowing across planes and down pipes a velvet revolution is taking place.
Experiments are almost as detailed as the numerical simulations, DNS is
yielding exact numerical solutions that one dared not dream about a decade
ago, and dynamical systems visualization of turbulent fluid's state space
geometry is unexpectedly elegant.
We shall take you on a tour of this newly breached, hitherto inaccessible
territory. Mastery of fluid mechanics is no prerequisite, and perhaps a
hindrance: the talk is aimed at anyone who had ever wondered why - if no
cloud is ever seen twice - we know a cloud when we see one? And how do we
turn that into mathematics?
