With walls look at the coanda effect, and also read up on the pitchfork bifurcation theory. You are sort of correct in that the flow should remain in the middle, but in most cases it doesn't. It will nearly always go the same way for a given mesh or experiment too, but we can't predict which way. The fact that we can influence the direction the jet takes with minimal force also provides us with some very powerful flow control abilities: it's the basis of a class of fluidic switches.
