Abstract
Experimental studies of the water-entry of cylinder bodies are conducted using high-speed camera to capture the splashes over the water surface and the subsurface cavity shapes during water entry and the cavity-running phase. Cavity evolution is discussed on single 140 conical cylinder body such as formation, development, and pinch-off of vertical and oblique entry. The dependence of the pinch-off type on the entry velocity is discussed for various entry speeds. The phenomena of two-body water entry in series and side-by-side are discussed in the end of this paper, and the data show that the spatial distance between the two bodies has a great influence on the development and the stability of the cavity and the dynamics of both bodies themselves.
