题目：Vanishing porosity limit of the coupled Stokes-Brinkman system
摘要：
In this talk, I will discuss with the small porosity asymptotic behavior of the coupled Stokes-Brinkman system in the presence of a curved inter\u0002face between the Stokes region and the Brinkman region. In particular, we derive a set of approximate solutions, validated via rigorous analysis, to the coupled Stokes-Brinkman system. Of particular interest is that the approximate solution satisfies a generalized Beavers-Joseph-Saffman\u0002Jones interface condition (1.9) with the constant of proportionality in\u0002dependent of the curvature of the interface. It is a joint work with Mingwen Fei and Xiaoming Wang.
