Numerical Simulation of a Water Column Deformation and Breakup by Shock Wave

Abstract

The numerical simulation of a water column breakup by shock wave is simulated. The sharp interface method that was constructed with level-set method and ghost fluid method was adopted as compressible two-phase flow numerical method. We simulate various Weber number conditions. The detail behavior of water column deformation is clarified by these simulations. Except the least Weber number for this paper, the tips are formed lateral side of a water column, deflected in flow direction by high-speed gas flow. In relatively large Weber number, the wavy shape is observed at upstream side interface. This wavy interface evolves with time.
