我们考虑不可压缩的Navier-Stokes方程在具有n大于或等于2的Rn的外部域中具有Dirichlet边界条件。我们比较了该初边值问题解的长时间行为与整个空间Rn中类似柯西问题解的长时间行为。我们发现这两个问题的解的长时间渐近性是重合的,无论是在弱Ln空间中的小初始数据的情况下,还是对于某类大初始数据。
We consider the incompressible Navier–Stokes equations with the Dirichlet boundary condition in an exterior domain of Rn with n⩾2 . We compare the long‐time behaviour of solutions to this initial‐boundary value problem with the long‐time behaviour of solutions of the analogous Cauchy problem in the whole space Rn . We find that the long‐time asymptotics of solutions to both problems coincide either in the case of small initial data in the weak Ln ‐space or for a certain class of large initial data.
