Fig.7. Comparison between the experimental observation and numerical simulation for a bubble near a rigid wall during the expansion phase (the dimensionless times for the simulation are: 0, 0.278, 0.553, 0.842 and 1.098, respectively. Horizontal and vertical axes of each frame are $-1.5 \leqslant r \leqslant 1.5$ and $-1.5 \leqslant z \leqslant 1.34$, respectively. The time scale is 1.66ms. The contours denote the pressure fields)
