This kind of drawing matches early year mechanical engineering courses. The generalizations are to add density distributions and the 3rd dimension. The math generalizes just fine for picking points that are stable. The motion on how it gets there relies on the full Navier Stokes vs the simplifications, so I wouldn't trust that you've actually gotten to the right stability point
