| 摘 要： | 海洋平台由拖船拖至工作地点,计算海洋平台的湿拖阻力在实际工程应用中具有重要意义。采用实验和数值模拟两种方法进行桁架式Spar平台的湿拖阻力性能研究,并将两种结果进行对比。并分析了桁架式Spar平台的垂荡板间流场的变化规律。研究结果表明,Spar平台的湿拖阻力中,摩擦阻力所占总阻力的比例小于10%;在平台拖曳运动的前几秒中,垂荡板间流体剧烈运动,速度和压力显著变化,随后就运动慢慢变缓;Spar平台在低速拖曳时会产生明显的波浪,尾部有回流。

| Abstract: | It is of great significance to obtain the towing resistance of offshore oil platforms in practical application because the offshore platforms are usually towed to the work location.After years of development,CFD has been used to calculate the practical ship resistance and optimize the hull line and so on.CFD are rarely used to calculate the towing resistance of offshore oil platforms because of the complex structures.Two methods are adopted here to calculate the towing resistance of a Truss Spar platform: experiment and numerical simulation.We get satisfactory results from the comparison of the results for towing resistance obtained by experiments and by CFD simulations.Additional analysis has been conducted to investigate the changes of flow fields between the heave plates of the Truss Spar platform. |
