Fig.6. Comparison between the experimental observation and numerical simulation for a bubble beneath a free surface during the toroidal bubble stage (the dimensionless times for the simulation are: 1.431, 1.453, 1.494 and 1.550, respectively. Horizontal and vertical axes of each frame are $-1.5 \leqslant r \leqslant 1.5$ and $-1.5 \leqslant z \leqslant 2.8$, respectively)   |
