Numerical Simulation of Wind Load on Marine Solar Photovoltaic Flexible Support
In order to further realize energy saving and emission reduction in the shipping industry,marine solar photovoltaic(PV)flexible supports can be laid on the deck surface of large oil tankers with open area and sufficient light.The wind load influencing factors and the distribution law of marine flexible supports are investigated by the numerical calculation method of computational fluid dynamics(CFD).The results show that the wind load of the PV array is inversely proportional to the longitudinal spacing,and when the longitudinal spacing ratio exceeds 1.8,the wind load of each row of PV panels basically does not change with the longitudinal spacing ratio,and at this time the difference in the value of the moment of each row of PV panels is less than 3 times.By increasing the number of longitudinal PV panels,the load distribution of PV panels in the middle position can be made more uniform.Based on the calculation results,when designing the marine flexible support,the first row can choose the steel cable with greater strength and arrange more than 15 rows of PV arrays,controlling the longitudinal spacing ratio of 1.8,in order to enhance the reliability of the structural in a targeted way,avoid the bending moment of the front row of PV panels exceeding the limit,and at the same time make the wind load distribution of PV panels of all rows more uniform.The relevant research results will provide the basis for the engineering design and arrangement of the marine flexible support.
