Non-ideal explosive underwater explosion shockwave model

The non-ideal behavior of aluminized explosives significantly affects the characteristics underwater explosion shockwaves, rendering classical model for shockwaves difficult to apply. In this paper, we analyze shockwave a new generation and propose explosive incorporating parameter correction function controlled by Al/O ratio. First, conducted tank experiments obtain four groups ratios parameters with analyzed effect ratio on them. Subsequently, calculated equation state established one-dimensional simulation explosion. We verified reliability mesh quality using experimental data. Finally, used calculate 0.1–1.3. Based data analysis, calculation pressure peak energy flow density containing non-ideality functions. Our results demonstrate that increase then decrease an in ratio, makes more sensitive proposed can better predict be high practical value as general structure models other or metalized explosives.
