Stirring and mixing: topology, optimization, and those pesky walls

Abstract:

I review various aspects of current research, both experimental and 
theoretical, on stirring and mixing in fluids. Three main threads are 
followed: 1) How topological features influence mixing effectiveness; 2) 
How this leads to novel optimization methods; and 3) How one has to be 
mindful of wall effects, which can dramatically slow down mixing.
