输运系数依赖温度的可压缩辐射流体解的整体存在性

摘要/Abstract

摘要：

该文主要研究了当粘性系数 $\lambda$ 和热传导系数 $\kappa$ 依赖于温度 $\theta$ , 即 $\lambda(\theta)=\theta^\alpha$ , $\kappa (\theta)=1+\theta^\beta$ , 其中 $\alpha\in[0, +\infty)$ , $\beta\in (2, +\infty)$ 时, 带有辐射项的可压缩 Navier-Stokes 方程解的全局存在性和非线性稳定性. 在关于参数 $\alpha$ 和初值的某些假设下, 该文得到了强解的全局存在唯一性. 此外, 在基于时间的一直估计下, 本文还证明了解的非线性指数稳定性. 需要指出的是, 如果 $\alpha$ 较小, 并且增长指数 $\beta$ 任意大, 则初值可以任意大.

Abstract:

In this paper, we are concerned with the the global existence and non-linear stability of the compressible and radiative Navier-Stokes matrixs when the viscosity $\lambda$ and heat conductivity $\kappa$ depend on temperature $\theta$ , i.e., $\lambda(\theta)=\theta^\alpha$ , $\kappa(\theta)=1+\theta^\beta$ with $\alpha \in [0, +\infty)$ , $\beta \in (2, +\infty)$ . The global existence and uniqueness of strong solutions are obtained under the assumptions on the parameter $\alpha$ and initial data. In addition, we also proved the non-linear exponential stability of the solutions on the basis of the fundamental uniform-in-time estimates. It should be note that the initial data could be large if $\alpha$ is small and the growth exponent $\beta$ can be arbitrarily large.
