船舶阻力是影响船舶快速性的重要因素。对于风电运维船来说，优异的快速性能是维持运维效率的保障。为提高该双体运维船的静水阻力性能，基于 CFD进行数值仿真，运用STAR-CCM+建立数值水池，进行静水阻力计算并研究不同片体间距对双体船阻力的影响。根据数值仿真结果设计船模拖曳试验与其对比，结果表明，采用STAR-CCM+对双体船的阻力数值计算精度较高，片体间距船长比k/L取0.3时较为合适。
Ship resistance is an important factor affecting ship rapidity. For wind power operation and maintenance ship, excellent fast performance is the guarantee to maintain operation and maintenance efficiency. In order to improve the resistance performance of the catamaran in still water, the numerical simulation is carried out based on CFD. The numerical pool is established by using STAR-CCM+ to calculate the hydrostatic resistance, and the influence of different sheet spacing on the resistance of catamaran is studied. According to the results of numerical simulation, the towing experiment of ship model is designed and compared. The results show that the numerical calculation accuracy of the resistance of catamaran is higher by using STAR-CCM +, and it is more suitable when the ratio of hull to length is 0.3.
