Reading the Wikipedia entry about the Navier–Stokes equation, and I don't understand this second term, the one with the outer product of the flow velocities. I mean, I understand the literal mathematical meaning, but I don't have an intuitive idea of what it physically represents. When I make up velocity fields and compute its value, I get something similar to the flow velocity but not exactly, and something related to divergence, but not exactly that either.
