题目：Homogenization problems in fluid mechanics

摘要：I will talk about homogenization problems in fluid mechanics --- the study of asymptotic behavior of fluid flows (governed by Stokes, Navier-Stokes or Euler equations) in domains perforated with a large number of tiny holes (obstacles). With an increasing number of holes, the fluid flow approaches an effective state governed by certain ”homogenized” equations which are homogeneous in form (without holes). The homogenized equation (or limit equation) is crucially determined by the ratio between the size of the holes and the mutual distance of the holes.

In this talk, I will introduce the background of this study and some known results. I will also recall my recent results in this research field and present some open problems.
