具有一般边界条件的Navier-Stokes-Fourier方程组

Navier-Stokes-Fourier system with general boundary conditions

Eduard Feireisl, Antonin Novotny

摘要:

本文考虑了有界区域$Ω\subset R^d$,$d=2,3$中的Navier-Stokes-Fourier方程组,该方程组具有物理上真实的流入/流出边界条件.我们提出了满足一般形式的相对能量不等式的弱解的新概念。对于任意有限能量的初值,该方程的弱解在时间上全局存在,并且满足弱-强唯一性原理。

英文摘要:

We consider the Navier--Stokes--Fourier system in a bounded domain $Ω\subset R^d$, $d=2,3$, with physically realistic in/out flow boundary conditions. We develop a new concept of weak solutions satisfying a general form of relative energy inequality. The weak solutions exist globally in time for any finite energy initial data and comply with the weak--strong uniqueness principle.
