We identify a class of measure-valued solutions of the barotropic Euler system on a general (unbounded) spatial domain as a vanishing viscosity limit for the compressible Navier–Stokes system. Then we establish the weak (measure-valued)–strong uniqueness principle, and, as a corollary, we obtain strong convergence to the Euler system on the lifespan of the strong solution.

通过测量值解决方案，可压缩的Navier–Stokes系统的粘度极限逐渐消失

我们将一类正压力欧拉系统在一般（无界）空间域上的度量值解确定为可压缩Navier–Stokes系统的消失粘度极限。然后，我们建立了弱（度量值）-强唯一性原理，并且作为推论，我们在强解的生命周期中获得了对Euler系统的强收敛性。
