| Abstract: | With a high speed camera, the time series of the process of liquid explosive dispersal with vertical dispersion are recorded with shadow method. By analyzing the fractal dimensions of the curve of the liquid front, it is presented that the curve of the liquid front in the process of liquid explosive dispersion exhibits self-similarity. |
