Hydrodynamic characterisation of offshore thin film FPV system based on discrete element approach
With the new round of energy revolution,offshore FPV becomes a new battlefield for new energy development.A numerical model of the offshore thin film FPV system is constructed using the spherical discrete element method,and the numerical calculation of the hydrodynamic characteristics is carried out under the conditions of different wave heights,peri-ods and structure diameters.The results validate the applicability of the numerical method for analysing the hydrodynamic characteristics of offshore thin film FPV systems.The results show that with the increase of wave height and structure dia-meter,the displacement,wave force and mooring force gradually increase;with the increase of period,the horizontal dis-placement decreases,the vertical displacement increases,the horizontal wave force increases and then decreases,the vertical wave force decreases at wave heights of H=4.0 m and H=5.0 m,and then increases at wave heights of H=5.0 m and H=5.5 m,and the mooring force at the facing side of the wave firstly increases and then decreases and that at the back of the wave firstly increases and then decreases and then decreases.In all working conditions,the horizontal wave force is greater than the vertical wave force,and the wave measurement mooring force is greater than the back wave side mooring force.
