| 摘 要： | 该文针对浮式平台系泊锚链，运用物理模型实验测得系泊无挡锚链在不同流态下的拖曳力系数CD，并分析其变化规律。运用CFD的方法，采用湍流模型LES和κ-ω SST，计算系泊无挡锚链的拖曳力系数CD，结合物理实验结果，比较分析得出较为精确的湍流模型。在此基础上，推算了实际海洋工程环境中系泊锚链拖曳力系数随雷诺数与来流方向的变化规律，并给出工程建议。

| Abstract: | For the mooring anchor chain of a floating platform, the towing force coefficient CD of mooring unchocked anchor chain under different flow states is measured by physical model experiment, and its variation law is analyzed. By using computational fluid dynamics (CFD) method, turbulence model LES and κ-ω SST were used to calculate the towing force coefficient CD of mooring unshielded anchor chain, and a relatively accurate turbulence model was obtained by combining the results of physical experiment. On this basis, the variation law of towing force coefficient of mooring anchor chain with Reynolds number and incoming flow direction in actual marine engineering environment is computed, and engineering suggestions are developed. |
