本文考虑混合边界条件下,三维定常Navier—Stokes方程.利用Galerkin逼近方法和差商方法,证明了弱解和强解的存在性.
In this paper, we consider the stationary Navier-Stokes equations with mixed boundary conditions in a bounded domain Ω R^3 . The existence of weak solution and strong solution are obtained using Galerkin approximation method and differential quotient method, respectively.
