借鉴Demmel和Wiedemann近期的工作\\(\cite{[DW]}\\),我们研究了仅具有水平耗散的三维Navier-Stokes方程弱解的能量平衡定律的有效性。我们证明了著名的Lions-Shinbrot型能量守恒准则(最初为经典各向同性Navier-Stokes方程建立)在该各向异性情形下仍然成立。此外,我们提出了两种不同的方法,分别处理环面情形和全空间情形。
英文摘要
In the spirit of the recent work by Demmel and Wiedemann \cite{[DW]}, we investigate the validity of the energy balance law for weak solutions to the three-dimensional Navier-Stokes equations with only horizontal dissipation. We prove that famous Lions-Shinbrot type energy conservation criteria, originally established for the classical isotropic Navier-Stokes equations, continue to hold in this anisotropic setting. Furthermore, we present two distinct approaches that handle the torus case and the whole space case, respectively.
