Abstract

The spar buoy wave energy model absorbs the wave energy by the self-oscillating motion of the floating body. The relative motion of the water column in the pipe was caused and the captured wave energy is converted by the added pneumatic damping. It can be studied as an oscillating single floating buoy. HydroStar hydrodynamics software is used to calculate the hydrodynamic performance of the straight center pipe model under different wave conditions. The effect of different added pneumatic damping on the Capture Width Ratio （CWR） of the model is compared and analyzed, and the optimal pneumatic damping is obtained. The performance of the model under three different total masses is studied, and the relationship between the optimal response wave period and the total mass of the model is obtained. The CWR of the spar buoy model was tested in a wave tank, and the experimental results obtained can further verify the numerical calculation results.
