An approach in modeling cavitating flows with gravity effect. (English) Zbl 0939.76009
Summary: We describe numerical investigations of submerged cavitating slender axisymmetric bodies with gravity effect. The developed cavity shape and the hydrodynamic characteristics of cavitating axisymmetric bodies are calculated. While these cavities originate from both the shoulder and the tail of bodies, we focus our main attention on the cavities originated from the shoulder. The boundary element method is used to solve the potential flow problem, and a new iteration method named adaptive modified Newton iteration is developed to determine the cavity shape.
