- Consideration is given to liquid impact in the supersonic regime in order to characterize pressure loading and other mechanisms which could damage a solid target such as a jet in flight. The liquid mass is treated as having a free surface, while the solid is assumed linear elastic. During contact, the fluid is maintained as a continuum and the solid becomes a homogeneous and isotropic elastic material. The processes have been described analytically and numerically by incompressible models, by water entry models, and with two-dimensional calculations. Experimentation has been performed with single and multiple impact techniques, with attention given to jetting, the jetting angle, impact pressures, and impacts on a wetted surface. High edge pressures have been observed, as has cavitation in the liquid and detachment of the edge shock. The presence of a liquid film on the surface of the object has been found to significantly affect the extent of erosion.
