本文研究了波浪条件下浮动直管的水动力行为。计算作用在小型漂浮结构上的力的主要问题是获得正确的力系数 Cn 和 Ct，这与水下结构不同。对于小尺寸的浮动直管，我们将其简化为二维问题，其中管道在波浪条件下对称设置。推导了波浪条件下的力方程，并提出了求解直浮管上波浪力的具体方法。将数值方法的结果与模型试验的结果进行了比较，并研究了 Cn 和 Cton 数值结果的影响。给出了在计算直浮管上的波浪力时选择正确的 Cn 和 Ct 值的建议。该结果对于研究重力笼系统的水动力行为具有重要价值。
This paper examines the hydrodynamic behavior of a floating straight pipe under wave conditions. The main problem in calculating the forces acting on a small-sized floating structure is obtaining the correct force coefficients Cnand Ct, which differ from a submerged structure. For a floating straight pipe of small size, we simplify it into a 2D problem, where the pipe is set symmetrically under wave conditions. The force equations were deduced under wave conditions and a specific method proposed to resolve the wave forces acting on a straight floating pipe. Results of the numerical method were compared to those from model tests and the effects of Cnand Cton numerical results studied. Suggestions for the selection of correct Cnand Ctvalues in calculating wave forces on a straight floating pipe are given. The results are valuable for research into the hydrodynamic behavior of the gravity cage system.
