本文研究定常Navier-Stokes方程-vdw+(wV)w=-vp在Jz中,(1.1)vw= o在Q中,(1.2)w= o在asz中,(1.3)4 × 3 Y)+ WCC在Q中无穷远处的解(w,p)的渐近结构. (1.4)这里Q是一个外部区域,Q= R2-K,其中K是一个具有光滑边界的紧集。我们将注意力限制在非零常数向量Wi上,并且在变量的适当旋转和缩放之后,我们将注意力限制在v= 1和Wi =(1,0)上。我们做一个标准的假设,即w=(u,u)有有限的狄利克雷范数:
In this paper we study the asymptotic structure of a solution (w, p) of the steady Navier-Stokes equations-vdw+(wV) w=-vp in Jz,(1.1) vw= o in Q,(1.2) w= o on asz,(1.3)4x3 Y)+ WCC at infinity in Q.(1.4) Here Q is an exterior domain, Q= R2-K, where K is a compact set with smooth boundary. We restrict attention to a non-zero constant vector w,, and after a suitable rotation and scaling of the variables, we restrict attention to v= 1 and w,=(l, O). We make the standard assumption that w=(u, u) has finite Dirichlet norm:
