Study On the Simulation Performance of Two-sided Segmented Wavemakers

Segmented wavemakers which consist of numerous individually programmed paddles have become important in the study of wave and its interaction with ocean engineering structures in ocean basin. There are some key problems greatly affecting the simulation quality of segmented wavemakers, including the limitation of direction angle of oblique wave simulation induced by paddle width and wave period, the generation of spurious waves and the effective test area of 3D shortcrested wave. The following results are obtained through the analysis of the performance of two-sided segmented wavemakers:(1)The relationship between oblique wave angle and wave period; (2)Wave direction limitation to prevent spurious waves; (3)Effective test area of simulated 3D short-crested wave. The results are significant to high quality wave simulation and providing better wave environment conditions for model tests of various ocean engineering structures in deep ocean basin.
