AI总结:

本文研究了3D非齐次不可压缩Navier-Stokes系统在临界尺寸穿孔区域中的均匀化问题,证明了当孔距参数ε趋于0时,速度与密度收敛于带Brinkman型摩擦项的Navier-Stokes系统解。

摘要:

本文研究3D非齐次不可压缩Navier-Stokes系统在具有临界尺寸孔洞的穿孔区域中的均匀化。孔洞直径为ε^3,其中ε是衡量孔洞间相互距离的小参数。我们证明当ε趋于0时,速度和密度收敛到带有Brinkman型摩擦项的非齐次不可压缩Navier-Stokes系统的解。

英文摘要:

In this paper, we study the homogenization of 3D non-homogeneous incompressible Navier-Stokes system in perforated domains with holes of critical size. The diameter of the holes is of size ε^3, where εis a small parameter measuring the mutual distance between the holes. We show that when εtends to 0, the velocity and density converge to a solution of the non-homogeneous incompressible Navier-Stokes system with a friction term of Brinkman type.
