Patterns in chaotic mixing
Joanne Deval, Patrick Tabeling · Physics World · 2000
Mixing is a problem that has been tackled by engineers, has fascinated physicists and has inspired philosophers for many years. In the chemical industry engineers have to struggle with mixing, knowing that empirical rules do not necessarily help when it comes to designing new equipment. The problem of mixing also challenges atmospheric scientists who are trying to reliably predict the path of pollutants circulating around the planet.
