Characterizing the Liquid Dispersion with Ansys LS-Dyna

The safety analyses of nuclear power plants are critical for ensuring the protection of both the facility and the surrounding infrastructure. One essential aspect of these analyses involves assessing the potential impact of aircraft on reactor containment structures. This assessment is crucial to understand the potential risks and to develop effective safety measures. A typical scenario considered in these analyses involves a large commercial aircraft impacting the reactor containment structure. To accurately predict the consequences of such an impact, e.g. fire hazard, it is necessary to study the sprays resulting from the impact of liquid-filled projectiles on hard walls.
