海上平台是开采海洋资源的关键建筑，而支撑柱在平台中起着至关重要的作用。本文建立在海水作用下支撑柱做单圆柱绕流、串列双圆柱绕流和并列双圆柱绕流的二维流场模型，运用大涡模拟方法，对这3种模型进行数值模拟，得出其瞬时流场速度云图和圆柱受力特性曲线图。模拟计算层流和湍流情况下的圆柱绕流，通过模拟结果分析流场、升力系数和阻力系数的变化规律。
The offshore platform is a key building for the exploitation of marine resources, and the support column plays a vital role in the platform. This article establishes that the support column is used to flow around a single cylinder, a series of double cylinders, and a parallel double cylinder under the action of seawater. The two-dimensional flow field model of the flow is numerically simulated using the large eddy simulation method to obtain the instantaneous flow field velocity cloud diagram and the cylindrical force characteristic curve diagram. Simulate and calculate the flow around a cylinder under laminar flow and turbulent flow, and analyze the flow field, lift coefficient and drag coefficient through the simulation results.
