Abstract
In the domain Ω ∋ ℝ3 with two exits at infinity, Ω1 = {x:∣x′∣<g 1(x 3),x 3 > 2} and Ω2 = {x:0<x 3<g 3(∣x′∣), ∣x′∣>2}, one investigates the stationary system of Navier-Stokes equations under the boundary condition
. One proves existence and uniqueness theorems for the solution of this problem with an infinite Dirichlet integral, under a given flow of the velocity vector across the cross sections of the exits at infinity. As an example one considers the case wheng i(t) ≡1.
