基于STAR-CCM+，采用$ k - \varepsilon $湍流模型对半潜式海洋平台进行三维数值模拟，计算海洋平台及压强分布，并通过与实验结果对比对本文算法进行验证。在此基础上，分析不同来流方向和不同来流速度下平台的阻力及表面压强的变化规律。结果表明：平台阻力受“遮蔽”效应和迎流面面积的影响较大；在相同来流速度下，不同方向的平台阻力随流向角度增大；相同来流方向下，平台阻力随着来流速度的增大而增大。
Based on STAR-CCM +, the three-dimensional numerical simulation of Semi-submerged platform is carried out by using turbulence model. The offshore platform and pressure distribution are calculated, and the algorithm is verified by comparing with the experimental results. On this basis, the variation laws of platform resistance and surface pressure under different inflow directions and velocities are analyzed. The results show that the platform resistance is greatly affected by the shielding effect and the area of the upstream surface. Under the same inflow velocity, the platform resistance in different directions increases with the inflow angle. Under the same inflow direction, the platform resistance increases with the increase of inflow velocity.
