Topological approaches to problems of stirring and mixing
Seminar Room 1, Newton Institute
AbstractI 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.
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
