摘要

In the present work we study the capabilities of a single segmented wavemalcer to generate multidirectional sea states. We want to reproduce typical West Africa sea conditions in a rectangular basin, that is two spectra representing swell and wind waves with ±45 degrees main directions relative to the axis basin. To that extent we study two generation techniques proposed respectively by Dalrymple and Molin which relie on the control of sidewall reflections in order to enlarge the testing zone. Both numerical and experimental results show that the use of such methods in combination with a single wavemaker provides high quality wavefields as well as large extent testing area. The Molin method appears to be more efficient in terms of wavefield quality within the testing area although the tuning of its setting parameters requires more care than the Dalrymple method.
