Abstract

This paper studies the boundary value problem on the steady compressible Navier-Stokes-Fourier system in a channel domain \((0,1)\times \mathbb {T}^2\) with a class of generalized slip boundary conditions that were systematically derived from the Boltzmann equation by Coron [9] and later by Aoki et al [1]. We establish the existence and uniqueness of strong solutions in \((L_{0}^{2}\cap H^{2}(\Omega ))\times V^{3}(\Omega )\times H^{3}(\Omega )\) provided that the wall temperature is near a positive constant. The proof relies on the construction of a new variational formulation for the corresponding linearized problem and employs a fixed point argument. The main difficulty arises from the interplay of velocity and temperature derivatives together with the effect of density dependence on the boundary.

具有滑移边界条件的稳定可压缩Navier-Stokes-Fourier系统
本文研究了通道域\((0,1)\times \mathbb {T}^2\)上稳定可压缩Navier-Stokes-Fourier系统的边值问题,该边值问题具有一类由Coron[9]和后来由Aoki等人从Boltzmann方程系统导出的广义滑移边界条件。当壁面温度接近一个正常数时,我们在\((L_{0}^{2}\cap H^{2}(\Omega ))\times V^{3}(\Omega )\times H^{3}(\Omega )\)中建立了强解的存在唯一性。该证明依赖于对相应的线性化问题构造一个新的变分公式,并采用不动点论证。主要的困难来自于速度和温度导数的相互作用以及密度对边界的依赖。

期刊介绍: The Journal of Mathematical Fluid Mechanics (JMFM)is a forum for the publication of high-quality peer-reviewed papers on the mathematical theory of fluid mechanics, with special regards to the Navier-Stokes equations. As an important part of that, the journal encourages papers dealing with mathematical aspects of computational theory, as well as with applications in science and engineering. The journal also publishes in related areas of mathematics that have a direct bearing on the mathematical theory of fluid mechanics. All papers will be characterized by originality and mathematical rigor. For a paper to be accepted, it is not enough that it contains original results. In fact, results should be highly relevant to the mathematical theory of fluid mechanics, and meet a wide readership.
