| Abstract: | An experimental device for the liquid explosive disseminations with constraints formed by up and down plains was set up. Applying the shadow photograph technology, the time series about the breakup shape of liquid-air interfaces were recorded. And using the PLIF (planar laser induced fluorescence) technology, the fluorescence photos about liquid shell expanding in radial direction were obtained. By means of digital image processing, fractal geometry and numerical simulation methods, systematic analyses to t... |
