可压缩Navier-Stokes方程粘性接触波与稀疏波叠加的稳定性

Stability of Superposition of Viscous Contact Wave and Rarefaction Waves for Compressible Navier-Stokes System

Feimin Huang, Teng Wang

摘要:

本文研究一维可压缩Navier-Stokes方程组解的大时间性态。我们证明了在\emph{large}初始扰动下,非等熵多熵气体的粘性接触波与稀疏波的组合是稳定的,只要组合波的强度适当小,绝热指数$γ$不需要接近1.

英文摘要:

This paper is concerned with the large-time behavior of solutions for the one-dimensional compressible Navier-Stokes system. We show that the combination of viscous contact wave with rarefaction waves for the non-isentropic polytropic gas is stable under \emph{large} initial perturbation without the condition that the adiabatic exponent $γ$ is close to 1, provided the strength of the combination waves is suitably small.
