Abstract
This paper is concerned with the global solutions of the 3D compressible micropolar fluid model in the domain to a subset of \begin{document}$ R^3 $\end{document} bounded with two coaxial cylinders that present the solid thermo-insulated walls, which is in a thermodynamical sense perfect and polytropic. Compared with the classical Navier-Stokes equations, the angular velocity \begin{document}$ w $\end{document} in this model brings benefit that is the damping term -\begin{document}$ uw $\end{document} can provide extra regularity of \begin{document}$ w $\end{document}. At the same time, the term \begin{document}$ uw^2 $\end{document} is bad, it increases the nonlinearity of our system. Moreover, the regularity and exponential stability in \begin{document}$ H^4 $\end{document} also are proved.
