Volume rendering of a liquid foam flowing through a constriction. The acquisition rate was set to five tomographic scans per second to resolve the flow in time and track the individual cells for a period of 27 s. In the volume rendering, each color represents a time frame of the flowing foam: t0 (yellow), t0 + 2 s (green), t0 + 4 s (blue). In (a) the overview image of the constriction is shown, in (b) the side view shows how individual bubbles progress in the vertical direction from the top towards the bottom of the flow cell (constriction) and in (c) the view from the bottom demonstrates the radial displacement of the bubbles towards the walls below the constriction.
