摘　　要：针对钻井船海上航行工程背景,考虑浮态变化对钻井船阻力的影响,采用粘性流体力学算法,对某艘有详细实验数据的钻井船在静水中的阻力性能进行计算与分析。通过研究网格划分形式与网格数量等因素对计算结果的影响,确定合理的网格划分方法,提高计算的准确性。之后,对一艘3 000 m深水钻井船进行计算,分析月池形状与航速等方面对钻井船阻力的影响,有较好的实际应用前景。Based on the navigation engineering background of drilling ships, the present study focuses on thecalculation and analysis of the calm water resistance of a drilling ship with the detailed experimental data by usingviscous computational fluid dynamics with the consideration of the influence of floating state on the resistance.The reasonable meshing topology is determined to improve the calculation accuracy by analyzing the influenceof the meshing topology and the grid number on the calculation results. Then, a 3 000-meter deep water drillingship is calculated to analyze the resistance performance under the different moonpool shapes and speeds. Theconclusion would have a better practical application prospect.
