Abstract The sensitivity of moving particle semi-implicit (MPS) simulations to numerical parameters is investigated in this study. Although the verification and validation (V&V) are important ensure accurate results, MPS has poor performance convergences with a time step size. Therefore, users need tune fit results into benchmarks. However, such tuning not always valid for other simulations...

This work evaluates the survivability of a point-absorbing wave energy converter at sea states along and inside 50-year environmental contour for selected-site in North Sea, by utilizing CFD simulations. Focused groups based on NewWave theory are used to model extreme waves. The numerical breaking waves have been previously predicted analytical criterion, showing that latter provides an accurat...

A semi-analytical model of hydroelastic slamming for two-dimensional symmetric flexible bodies is presented in this paper. The hydrodynamic loads are computed using the analytical Modified Logvinovich Model (MLM) with account elastic deflections body surface. described by modal approach. rigid and motions at same time together wetted part coupled problem impact reduced to a system nonlinear ord...

The increasing importance of the sustainability challenge in ocean engineering has led to the development of floating structure of various configurations. In this study, a numerical wave tank based on the Navier-Stokes equations has been established. The turbulence model, namely standard k-ε is incorporated to the numerical tank to broaden applicability of simulation. The VOF method has been wi...
