A Regularized Interface Method to examine the shock interaction with cylindrical water column

The interaction of a planar shock wave with a liquid water column induces aerodynamic breakup, transversal jets, and liquid evaporation. These phenomena are affected by hydro-thermodynamic processes due to the shock passage through the liquid water column. To examine these processes, a recently developed Regularized Interface Method (RIM) is employed. This allows resolving the complex interfacial dynamics of evaporation and surface tension. In addition, an equation of state (EOS) that accurately models the fluid phase behavior and the interface derivative properties is considered. Within this framework, RIM is employed to examine a set of different Mach numbers and cavity sizes. The morphology of the interfacial structures and the induced flow features are then discussed and compared with previous experimental and numerical studies.
