摘要
针对三浮筒型式和四浮筒型式的全潜型浮式风机拖航过程,设置4种不同的数值模拟工况,对比研究在相同的波浪环境及相同的拖航速度条件下,海流速度对浮式风机拖航运动性能的影响,为实际工程提供参考。结果表明:流速对两种结构型式的浮式风机垂荡的影响较小,四浮筒型式的全潜型浮式风机因具有较大的底面积而使其在相同工况下的垂荡幅值较小。在不同流速下,两种结构型式浮式风机的横摇和纵摇角都在±3°内波动。流速对拖缆力的影响较大,在0.5 m/s流速下,航速为2 m/s时四浮筒型式的全潜型浮式风机的拖缆力最大值为3.31 MN,较三浮筒型式浮式风机增加了8.96%。
In this paper, four different flowing velocities on the water surface are designed in a same wave environment for comparatively studying towing process of a three-column submerged floating offshore wind turbine(SFOWT) and a four-column one respectively. The results show that the surface flowing speed has only little effect on the heave of the SFOWT;the roll and pitch angles of the two types of floating turbine are within ±3°, but there is a greater influence on the towing force. Under towing speed of 2 m/s and flowing speed of 0.5 m/s, the maximum towing force of the four-column SFOWT is 3.31 MN, having an increase of 8.96% compared with the three-column SFOWT.
