In Figure four, the response amplitude of each and every windward module from the three models All 3 curves of various module numbers showed a comparable trend, with only a slight is shown. All 3 curves of various module numbers showed a related trend, with disturbance occurring around 1.8. In the multi-module model, the RAOs of the windward only a slight disturbance occurring about 1.eight.
