摘要/Abstract

摘要： 结合3类内孤立波理论模型KdV、eKdV和MCC与Morison公式和压差力公式，建立了南海八号深水半潜式平台的内孤立波载荷预报方法.利用大型内波水槽开展了南海八号深水半潜式平台的内孤立波载荷模型实验，分析了Morison公式中南海八号深水半潜式平台的惯性力系数和拖曳力系数.结果表明，Morison公式中的惯性力系数和拖曳力系数不仅与雷诺数Re、KC(Keulegan-Carpenter)数以及两层流体的上下层厚度比有关，而且与平台的结构形式有关.对于南海八号深水半潜式平台，Morison公式中的惯性力系数与KC数之间呈幂函数关系，拖曳力系数与Re之间呈指数函数关系.

Abstract: A prediction method is established for internal solitary wave loads on NANHAI 8 semi-submersible platform based on internal solitary wave theory, Morison equation and pressure integral. A series of experiments were carried out to study the internal solitary wave loads in a wave flume. The inertial and drag coefficients in Morison equation for the platform have been determined by experimental results. It shows that the coefficients are not only related to Re number, KC (Keulegan-Carpenter) number and the layer thickness ratio, but also affected by the platform structures. The inertia coefficient decreases with KC number in power function, while the drag coefficient decreases with Re number in exponential function.

Key words: semi-submersible platform, internal solitary wave, model test, inertial coefficient, drag coefficient
