... ABSTRACT In the present work, a HOS-CFD coupled method is validated with wave-structure interaction. The HOS-CFD method is applied to simulate a fixed CALM buoy in regular waves with overset grids. Firstly, a periodic wave simulation is carried out to make a better parameter choice in HOS-CFD...

The paper considers the experimental setup and equipment used, presents the main results of the studies. The obtained data were analyzed to explain...

... Technologies have the above-mentioned characteristics and OceanScan-MST developed a device called Manta Gateway that, mounted on a buoy or ASV, acts as a bridge between Wi-Fi, mobile broadband, Iridium communications and acoustic signals for long-range underwater transmission. scaradozzi communication...

... as the predominant culture and harvesting method for mussels. It can be used in a variety of environments ranging from enclosed areas to offshore sites. The systems used vary in length and usually consist of two parallel ropes, so called backbones, supported by buoys. The cultivation rope for the mussel growth hangs...

... ABSTRACT Accurate prediction of the motion of a wave energy converter and the loads acting on it is of great significance in the design procedure. In this work, the interaction between focused waves and a hemispherical-bottomed buoy is simulated using the in-house CFD solver naoe-FOAM-SJTU...
