摘要:

本文研究了$3D$不可压Navier-斯托克斯方程弱解的正则性准则,并考虑了边界效应.本文证明了正则区域上一类斜导数边界条件的边界正则性定理,条件是流体的涡量是相干排列的。特别是,我们建立了边界规则的圆球,半空间和直圆柱管道,受经典的Navier和运动学边界条件。

英文摘要:

We study the regularity criteria for weak solutions to the $3D$ incompressible Navier--Stokes equations in terms of the geometry of vortex structures, taking into account the boundary effects. A boundary regularity theorem is proved on regular domains with a class of oblique derivative boundary conditions, providing that the vorticity of the fluid is coherently aligned. In particular, we establish the boundary regularity on round balls, half-spaces and right circular cylindrical ducts, subject to the classical Navier and kinematic boundary conditions.
