Abstract

Abstract

Ejecta mixing takes place at the meta-gas interface under strong shock, where the breakup of ejected particles is a very important affecting factor. By adopting Taylor analogy breakup (TAB) model, the breakup effect of the melted lead on its transportation in helium gas was analyzed. The calculation adopted the two-phase flow (including gas and particle) numerical program. From the simulation results, some significant mechanical quantities were obtained, including the breakup time and sizes of the ejected particles. Meantime, the lead ejecta mixing process was simulated considering that the particle breakup was consistent with the experiments. These results give some important references in understanding the process of ejecta mixing.
