摘要:

研究了圆柱外定常Navier-斯托克斯方程无旋轴对称解的渐近性态。在速度具有广义有限狄利克雷积分的假设下,我们证明了涡量的一个先验衰减估计。作为应用,我们得到了一个Liouville型定理.

英文摘要:

We study the asymptotic behavior of axisymmetric solutions with no swirl to the steady Navier-Stokes equations in the outside of the cylinder. We prove an a priori decay estimate of the vorticity under the assumption that the velocity has generalized finite Dirichlet integral. As an application, we obtain a Liouville-type theorem.
