Topological approaches to problems of stirring and mixing

Thiffeault, J-L (University of Wisconsin-Madison)
Thursday 26 July 2012, 09:00-09:40

Seminar Room 1, Newton Institute


I will review two topological approaches to stirring and mixing. The first involves constructing systems such that the fluid motion is topologically complex, usually by imposing a specific motion of rods. I will discuss optimization strategies that can be implemented. The second is diagnostic, where flow characteristics are deduced from observations of periodic or random orbits and their topological properties.
