全Navier-Stokes-Fourier方程组的弱-强唯一性

Weak-strong uniqueness property for the full Navier-Stokes-Fourier system

Eduard Feireisl, Antonin Novotny

摘要:

描述可压缩、粘性和导热流体运动的Navier-Stokes-Fourier方程组对于任何有限能量的初始数据都具有时间上的全局弱解。我们表明,一个弱解与强解一致,从相同的初始数据,只要后者存在。特别地,强解在弱解类中是唯一的。

英文摘要:

The Navier-Stokes-Fourier system describing the motion of a compressible, viscous, and heat conducting fluid is known to possess global-in-time weak solutions for any initial data of finite energy. We show that a weak solution coincides with the strong solution, emanating from the same initial data, as long as the latter exists. In particular, strong solutions are unique within the class of weak solutions.
