Behavior at low and moderate flow rates

When two opposing streams of water meet at a cross-junction at low flow rates (left), the streams part and continue flowing symmetrically, which causes cells to elongate when in the center. When the flow rate is increased to a moderate flow (right), small instabilities in the flow are compounded. This results in the formation of a swirling spiral vortex, which deforms cells in the center of the cross-junction.
