外圆形域上局部近边界解析解的Navier-斯托克斯方程的无粘极限

The inviscid limit of Navier-Stokes equations for locally near boundary analytic data on an exterior circular domain

Toan T. Nguyen, Trinh T. Nguyen

摘要:

Caflisch和Sammartino在他们的经典工作[20]中建立了半空间上不可压缩Navier-斯托克斯方程解析数据的黏性解的无粘极限和边界层展开式。随后在他们的Comptes rendus文章[4]中宣布,结果可以扩展到包括外部圆形域上的分析数据,但文献中似乎缺少证明。扩张到外部区域面临一个基本困难,即相应的线性半群在解析空间中可能不像在半空间中那样是压缩的[19]。在本文中,我们解决了一个更大的初始数据类这个开放的问题。该决议是由于这样的事实,它足以传播的解决方案,解析只有在边界附近,在最近的作品,涉及边界涡度制定,解析估计的格林函数,适应测地坐标附近的边界,和Sobolev解析迭代计划的框架。

英文摘要:

In their classical work [20], Caflisch and Sammartino established the inviscid limit and boundary layer expansions of vanishing viscosity solutions to the incompressible Navier-Stokes equations for analytic data on a half-space. It was then subsequently announced in their Comptes rendus article [4] that the results can be extended to include analytic data on an exterior circular domain, however the proof appears missing in the literature. The extension to an exterior domain faces a fundamental difficulty that the corresponding linear semigroup may not be contractive in analytic spaces as was the case on the half-space [19]. In this paper, we resolve this open problem for a much larger class of initial data. The resolution is due to the fact that it suffices to propagate solutions that are analytic only near the boundary, following the framework developed in the recent works that involve the boundary vorticity formulation, the analyticity estimates on the Green function, the adapted geodesic coordinates near a boundary, and the Sobolev-analytic iterative scheme.
