随着船舶制造和运输行业的持续发展,单一的海洋浮式结构物已无法满足开发生产的实际需求,将面临更多有关于多浮体协同作业的问题.本文基于粘流理论以及计算流体力学(CFD)理论,并采用基于全六面体非结构化网格技术求解粘性雷诺数平均方程的自由液面捕捉法,利用较成熟的CFD商业软件FINE/Marine,对两固定浮式结构窄缝间的流场问题进行数值模拟,并通过观察窄缝间流场的波面升高,对比分析不同波浪周期(波浪频率)、不同窄缝间距对窄缝间流场的影响,并对窄缝间流场的水动力共振问题进行规律探索.最后,本文对不同模型参数的模拟结果进行对比探究.%With the continuous development of the ship manufacturing and transportation industry, the single floating structure can not meet the actual demand of the development and production. Based on viscous fluid mechanics and compu-tational fluid dynamics, flow field in the narrow gap of two fixed floating structures is simulated numerically in this thesis via a kind of commercial CFD software called FINE/Marine, and its computational result is also analyzed. Based on all-hexahed-ral and unstructured mesh generation technique which is used to solve averaged equations of viscous Reynolds number, a kind of free surface capture is adopted in this thesis. The influence on flow field in narrow gap from different distances between structures and different wave frequencies is analyzed and compared via observing wave elevation. The exploration of hydrodynamic resonance is also carried out in this thesis. Finally, the simulation results of different model parameters are compared and analyzed.
