Summary: We consider the stationary Navier-Stokes equations in a 2-dimensional Y-shape infinite channel involving the general outflow condition. Assuming that the domain and the data are symmetric with respect to a straight line, and that the line of symmetry intersects every boundary component where the boundary integral does not vanish, we show the existence of symmetric solutions. We report also the regularity and the asymptotic behavior of the solution.
