关于可压缩原始方程的弱-强唯一性和奇异极限

On weak-strong uniqueness and singular limit for the compressible Primitive Equations

Hongjun Gao, Sarka Necasova, Tong Tang

摘要:

研究了可压缩原始方程的弱-强唯一性和奇异极限。我们发现,一个弱解符合强解源自相同的初始数据。另一方面,我们证明了在低马赫数和大雷诺数的情况下,在充分准备的初始数据的情况下,可压缩PE将接近不可压缩无粘PE方程。据作者所知,这是第一个工作之间的桥梁可压缩PE不可压缩无粘PE的联系。

英文摘要:

This paper addresses the weak-strong uniqueness property and singular limit for the compressible Primitive Equations (PE). We show that a weak solution coincides with the strong solution emanating from the same initial data. On the other hand, we prove compressible PE will approach the incompressible inviscid PE equations in the regime of low Mach number and large Reynolds number in the case of well-prepared initial data. To the best of the authors' knowledge, this is the first work to bridge the link between the compressible PE with incompressible inviscid PE.
