摘要

SIAM 数学分析期刊》，第 56 卷第 4 期，第 5099-5143 页，2024 年 8 月。摘要。我们研究不可压缩纳维-斯托克斯方程的统计解及其粘度消失极限。我们证明了使用相关测量法的公式 [U. S. Fjordholm, J. M.S. Fjordholm, S. Lanthaler, and S. Mishra, Arch.Ration.Mech.Anal., 226 (2017), pp. 809-849] 和矩方程等价于 Foiaş-Prodi 意义上的统计解。在允许间歇性修正的弱缩放假设（即柯尔莫戈罗夫小尺度自相似性假设的弱化版本）下，我们证明了极限是不可压缩欧拉方程的统计解。为了达到极限，我们推导出了统计解的 Kármán-Howarth-Monin 关系，并将其与弱比例假设和相关量的紧凑性定理结合起来[U. S. Fjordholm et al.S. Fjordholm 等人，Math.模型方法应用科学》，30 (2020)，第 539-609 页]。

On the Vanishing Viscosity Limit of Statistical Solutions of the Incompressible Navier–Stokes Equations

SIAM Journal on Mathematical Analysis, Volume 56, Issue 4, Page 5099-5143, August 2024.
Abstract. We study statistical solutions of the incompressible Navier–Stokes equation and their vanishing viscosity limit. We show that a formulation using correlation measures as in [U. S. Fjordholm, S. Lanthaler, and S. Mishra, Arch. Ration. Mech. Anal., 226 (2017), pp. 809–849] and moment equations is equivalent to statistical solutions in the Foiaş–Prodi sense. Under the assumption of weak scaling, a weaker version of Kolmogorov’s self-similarity at small scales hypothesis that allows for intermittency corrections, we show that the limit is a statistical solution of the incompressible Euler equations. To pass to the limit, we derive a Kármán–Howarth–Monin relation for statistical solutions and combine it with the weak scaling assumption and a compactness theorem for correlation measures from [U. S. Fjordholm et al., Math. Models Methods Appl. Sci., 30 (2020), pp. 539–609].

期刊介绍： SIAM Journal on Mathematical Analysis (SIMA) features research articles of the highest quality employing innovative analytical techniques to treat problems in the natural sciences. Every paper has content that is primarily analytical and that employs mathematical methods in such areas as partial differential equations, the calculus of variations, functional analysis, approximation theory, harmonic or wavelet analysis, or dynamical systems. Additionally, every paper relates to a model for natural phenomena in such areas as fluid mechanics, materials science, quantum mechanics, biology, mathematical physics, or to the computational analysis of such phenomena. Submission of a manuscript to a SIAM journal is representation by the author that the manuscript has not been published or submitted simultaneously for publication elsewhere. Typical papers for SIMA do not exceed 35 journal pages. Substantial deviations from this page limit require that the referees, editor, and editor-in-chief be convinced that the increased length is both required by the subject matter and justified by the quality of the paper.
