Do the simulations and experiments agree?
Our experiments and conclusions agree very well with the simulations carried out by Prof. Clive Fletcher and his group. The sinking bubbles in the experiments seem to be slightly larger than in the simulations. The experiments also suggest that the bubbles inside (that go up) seem to be nearer to the walls in the experiments. An interesting detailed comparison would come from looking just below the head, where we see almost equal numbers of bubbles going up and down.
