This paper presents the results of potential-based methods and computational fluid dynamics (CFD) for the water-entry impact of a wedge and ship-like section. In the potential-based computation, a Generalized Wagner Model (GWM) and a Modified Logvinovich Model (MLM) were used. In the CFD computations, a constrained interpolation profile (CIP)-based method and commercial software were used for the prediction of fully nonlinear slamming phenomena. The grid convergence index for the peak pressure was analyzed for both CFD computations. The computational results were also compared with the experimental results obtained by the Korea Research Institute of Ships and Ocean Engineering (KRISO) as part of the Wave Induced Loads on Ships Joint Industry Project-III (WILS JIP-III). In the experiment, free drop tests were performed for 2-D wedges and ship sections of a containership. Accuracy was investigated in terms of the peak pressure, pressure distribution, local hydrodynamic force, and free-surface shape.
