Travelling waves in a non-linear flow network. Each panel displays different time frames. The network is represented by black lines while the colour around each node indicates the volume that has accumulated at that node. The red and blue nodes maintain a constant pressure difference (similar to connecting them to a pressure pump). The way in which the wave begins to form around the blue node, how it grows and travels to the red node can be observed. This process is repeated periodically, resulting in oscillations.
