“…Wave annihilation refers to the setup of a wave dissipation zone in the outlet area of a numerical pool to prevent wave reflection from affecting the waveform and calculations in the calculation area. In this study, a damping absorber [17] is used to set a distance of length λ at the outlet end of the pool as a damping absorber zone.…”

In this study, with respect to wave energy generation technology, a new scheme is proposed for oscillating-buoy type wave energy conversion. A three-dimensional model of a power generation device is established based on SolidWorks, and a three-dimensional viscous numerical pool is setup using STAR-CCM+ to facilitate the simulation analysis of the device. The hydrodynamic performance and energy capture characteristics of the device were examined using theoretical analysis and numerical simulations. The regularities of parameters, such as motion response, force, and output power of the device, were analysed under four wave environments with different time periods (T) and wave heights (H). The analysis and conclusions can be utilised as a reference for studying the hydrodynamic performance of wave power generation devices.

“…The Australian-developed "Poseidon" cylindrical float serves as an example of an oscillating float wave power generator. Alan Arthur Wells [19,20], the British engineer specializing in structural engineering, developed the innovative Wells turbine, which operates on lowpressure head air. A detailed representation of the turbine's structure can be observed on the lower left side of Figure 2.…”

A novel float-type device for wave energy power generation, designed specifically for offshore wave environments, is introduced as an innovative technology in wave energy utilization. Herein, we present the design concept, structural composition, and energy conversion process of the device, and conduct mathematical modeling and theoretical research on its kinematic and dynamic characteristics. At the same time, we use a numerical wave pool based on the STAR-CCM+ boundary wave making method and damping dissipation method to analyze the motion response and output power of the wave energy generator in a five-order Stokes wave environment within one wave cycle and the entire operating cycle. Finally, in order to develop the best design strategy, we study the effect of changing the structural parameters of the power generation device on the hydrodynamic performance of the device.

“…Waves were generated in a numerical wave pool in a fifth-order wave model at the velocity inlet and propagated in the x direction toward the pressure outlet. In order to reduce the reflection of waves at the boundary and more accurately simulate the interaction between waves and structures, damping wave dissipation was introduced [24]. The damped wave dissipation model provided by STAR-CCM+ was adopted to eliminate the waves.…”

In order to quantitatively analyze the data measurement accuracy of ocean buoys under normal and extreme sea conditions, in this study, we simulated the six-degree-of-freedom motion response of self-designed ocean buoys under different sea conditions based on a separated vortex simulation and the fluid volume method and analyzed the impact of the unsteady motion of buoys on data measurement. The results indicate that under normal sea conditions, the deviation between the numerical method used in this paper and the experimental results is less than 10%. The heaving motion of a buoy is most sensitive to changes in wave conditions. The fluctuation intensity of buoy motion is modulated by the height and wavelength of waves. When the wave height and wavelength are similar to the overall geometric size of a buoy, the wave characteristics of the buoy’s heave, yaw, and pitch motion are significant. In addition, under extreme sea conditions, the movement of the buoy can also cause a deviation in the measured velocity in the transverse flow direction, but the overall deviation is less than 10%. In extreme sea conditions, the wind speed measurement results should be corrected to improve the measurement accuracy of a buoy.
