Simulation of Water Entry of a Free-falling Wedge by Improved MPS Method.

In the present study, the process of free-falling wedge imparting on water is numerically studied by our in house solver based on Moving Particle Semi-Implicit (MPS) method. Some improved schemes are used in this solver to suppress numerically unphysical pressure oscillation in traditional MPS method. For validation purpose, computational results of wedge with different tilting angles are compared against experimental results from the Wave Induced Loads on Ships Joint Industry Project III (WILS J1P-III). Numerical pressures, free surface elevations and velocities of wedge show agreement with experimental data. [ABSTRACT FROM AUTHOR]
