摘要
以圆碟形上浮结构为研究对象,介绍其水动力性能研究现状,并使用计算流体力学方法分析圆碟形结构的水平方向阻力性能,进而对比2种不同主动推力模拟方法下的圆碟形结构的水平运动稳定性。同时,针对复杂海洋环境中该结构受复杂海流冲击可能造成的倾覆,进行了海流影响下的模拟分析,结果表明,圆碟形水下上浮结构具有较低的阻力,在受主动推力及海流影响下能保持良好的运动稳定性,这为预报圆碟形结构水动力性能和运动情况提供了参考。
The research status of the hydrodynamic performance of the floating disk structure is introduced,and the horizontal resistance performance of the disk structure is analyzed by using computational fluid dynamics method,and the horizontal motion stability of the disk structure under two different active thrust simulation methods is compared.At the same time,in view of the possible overturning caused by the impact of complex ocean currents,the simulation analysis under the influence of ocean currents is carried out.The results show that the disk-shaped underwater floating structure has low resistance and can maintain good motion stability under the influence of active thrust and ocean currents,which provides a reference for predicting the hydrodynamic performance and motion of the disk structure.
