Navier-斯托克斯方程时间周期解的空间渐近结构

On the spatially asymptotic structure of time-periodic solutions to the Navier-Stokes equations

Thomas Eiter

摘要:

研究了具有漂移项的Navier-斯托克斯方程的弱时间周期解在三维全空间中的渐近性态。将速度场分解为与时间无关的部分和剩余部分,并导出这两部分及其梯度的单独的渐近展开。我们观察到在空间无穷远处的行为是由相应的Oseen基本解决定的。

英文摘要:

The asymptotic behavior of weak time-periodic solutions to the Navier-Stokes equations with a drift term in the three-dimensional whole space is investigated. The velocity field is decomposed into a time-independent and a remaining part, and separate asymptotic expansions are derived for both parts and their gradients. One observes that the behavior at spatial infinity is determined by the corresponding Oseen fundamental solutions.
