摘要

辐射全欧拉方程是辐射流体力学中的一个基本系统,在天体物理和核现象中有许多实际应用,本文致力于研究防渗壁上非滑动边界条件下辐射全欧拉方程的初始边界值问题。由于防渗边界上的速度消失带来的困难,可压缩 Navier-Stokes 方程的结果很少,而辐射欧拉方程目前还没有结果。因此,本文证明的稀释波渐近稳定性是第一个关于非滑动边界条件下辐射欧拉方程解全局稳定性的严谨结果。这也有助于我们在[5]、[6]等系列论文中对具有辐射效应和不同边界条件(如流入/流出问题和不渗透边界问题)的稀释波渐近行为进行系统研究。

Asymptotic stability of rarefaction wave with non-slip boundary condition for radiative Euler flows

This paper is devoted to studying the initial-boundary value problem for the radiative full Euler equations, which are a fundamental system in the radiative hydrodynamics with many practical applications in astrophysical and nuclear phenomena, with the non-slip boundary condition on an impermeable wall. Due to the difficulty from the disappearance of the velocity on the impermeable boundary, quite few results for compressible Navier-Stokes equations and no result for the radiative Euler equations are available at this moment. So the asymptotic stability of the rarefaction wave proven in this paper is the first rigorous result on the global stability of solutions of the radiative Euler equations with the non-slip boundary condition. It also contributes to our systematical study on the asymptotic behaviors of the rarefaction wave with the radiative effect and different boundary conditions such as the inflow/outflow problem and the impermeable boundary problem in our series papers including [5], [6].
