This work is part of a project for evaluating catastrophic tank failures caused by impacts with a high-speed solid body. Previous studies on shock overpressure and drag events have provided analytical predictions, but they are not sufficient to explain ejection of liquid from the tank. This study focuses on the hydrodynamic behavior of the liquid after collision to explain subsequent ejection of liquid.

We find that prior to liquid ejection several well-defined phases occur, including the phenomenon known as the "hydraulic ram." Then a catastrophic tank failure leads to liquid ejection and fragmentation.
