Dispersion at Large Péclet Number

  • Yves Pomeau
Part of the NATO ASI Series book series (NSSB, volume 373)

Abstract

This is a review of results on the dispersion at large Péclet number in flows with a stationary structure. Therein, the molecular diffusion acts like a singular perturbation: although small, in the long run it makes its effects felt at order one. The two basic situations I will consider are: 1) dispersion in spatially periodic parallel rolls; 2) the settling of small particles in periodic rolls.
