Figure 13.
Snapshots of the bubble cloud during the simulation using the three-dimensional model. (a) initial condition, (b) t = 37 μs (during the passage of the wave), (c) t = 53.6 μs (timing at the maximum cloud volume) and (d) t = 65 μs (after the passage of the wave during the collapse). Four quantities are shown: the surface of bubbles by black color; iso-contour of void fraction with a value of 10−3 by white color; pressure iso-contours with the values of −105 and 105, by blue and red colors. The bar charts at right show the the distribution of bubble size in the proximal and distal halves of the cloud at the corresponding times.
