研究船舶的快速性和阻力性能对船型设计和优化有重要意义。本文以1艘海洋多功能双体船为研究对象，使用CFD软件STAR-CCM+计算双体船在静水航行中的阻力以及不同工况下的波浪增阻，并和二因次换算法、三因次换算法的计算结果进行对比，分析总阻力系数和航速之间的关系以及波浪增阻随波长的关系，得出双体船在航速为20kn时的总阻力系数达到峰值以及在λ/L=1.25时的波浪增阻系数达到峰值。计算表明，使用STAR-CCM+软件对双体船快速性和阻力性能的预报，具有计算速度快、精度高的优点，可以在对双体船阻力估算中推广应用。
It is important to study the fast and resistance performance of ships for ship design and optimization. In this paper, we use a multifunctional marine catamaran as the object of study, and use the CFD software STAR-CCM+ to calculate the resistance of the catamaran in hydrostatic navigation and wave added resistance under different working conditions, and compare it with the calculation results of quadric conversion and three-dimensional extrapolation, and analyze the relationship between the total resistance coefficient and navigation speed and the relationship between wave added resistance and wavelength, the results indicate that the total resistance coefficient peaks of the catamaran at a navigation speed of 20kn, The wave added resistance coefficient peaks at the λ/L=1.25, The calculations show that the use of STAR-CCM+ software for the prediction of catamaran fast and resistance performance has the advantages of fast calculation speed and high accuracy, which can be promoted and applied in the estimation of catamaran resistance performance.
