关于定常普朗特边界层展开的注记

Remarks on the Steady Prandtl Boundary Layer Expansions

Chen Gao, Liqun Zhang

摘要:

我们继续研究了\cite{GZ}中Prandtl边界层展开式的有效性,通过对余项流函数的估计,证明了当区域宽度较小时,Euler流是否是剪切流的扰动。本文给出了流函数在远离边界层处的一个新的导数估计,并证明了在区域宽度较小的情况下,展开式对任意非剪切Euler流的有效性。

英文摘要:

We continue the study of the validity of the Prandtl boundary layer expansions in \cite{GZ}, where by estimating the stream-function of the remainder, we proved if the Euler flow is perturbation of shear flows when the width of domain is small. In this paper, we obtain a new derivatives estimate of stream-function away from the boundary layer and then prove the validity of expansions for any non-shear Euler flow, provided the width of domain is small.
