文摘

In this paper, we consider the effect of external force on the large-time behavior of solutions to the Cauchy problem for the three-dimensional full compressible Navier–Stokes equations. We construct the global unique solution near the stationary profile to the system for the small H²(R³)$H^2\left({\mathbb{R}}^3\right)$ initial data. Moreover, the optimal L^p$L^p$–L²$L^2$1348a6d338f34beee4c883820">$(1\le p\le 2)$ time decay rates of the solution to the system are established via a low frequency and high frequency decomposition.
