摘要
该文针对海洋平台主体部分基本的四柱体结构物,基于CFD数值方法,应用结构化网格和SST k-ω湍流模型进行非定常的数值模拟。通过对比试验数据,验证了计算结果的可靠性,并以此为基础研究了不同来流角度与不同间距组合下四柱体结构物的流场形式和水动力系数规律,分析了四柱体结构物的流场干扰机理。
In this paper, the flow interaction of four-column structure is simulated with CFD method using structured grid and SST k- co turbulent model. The results are compared with experimental date to verify the numerical method. Then the turbulent flow around four-column structure with different spacing ratios under the two Reynolds numbers is investigated by analyzing the flow patterns and hydrodynamic coefficients.
