可压缩Navier-斯托克斯方程Cauchy问题解的强接触间断渐近性

Asymptotic behavior of solutions toward the strong contact discontinuity for compressible Navier-Stokes equations with Cauchy problem

Tingting Zheng

摘要:

本文考虑非等熵理想多方Navier-斯托克斯方程的Cauchy问题。在初始扰动部分较小但接触间断强度可以适当增大的条件下,建立了接触间断的渐近稳定性。利用这些条件,可以从复杂的Navier-斯托克斯方程结构中得到密度和温度的界。用初等能量法给出了证明。

英文摘要:

In this paper, we consider the nonisentropic ideal polytropic Navier-Stokes equations to the Cauchy problem. The asymptotic stability of contact discontinuity is established under the condition that the initial perturbations are partly small but the strength of contact discontinuity can be suitably large. With this conditions, the bounds of density and temperature can be obtained from the complicated structure of Navier-Stokes equations. The proofs are given by the elementary energy method.
