Numerical Models of Water Impact

This paper presents a numerical method for studying water impact of a two-dimensional body of arbitrary cross-section. The global simulation procedure based on the boundary element method is constructed. The attention is focused on the computational description of the jet flow in the framework of a potential flow assumption. The proposed computational model makes the numerical analysis more stable, in addition, enables the simulation of the flow deformation due to the gravity effect. Water impact problems due to the vertical impulsive motion of an initially floating body are considered. The prediction of hydrodynamic pressure is found to be in good agreement with similarity solutions for wedges with different dead-rise angle.
