摘 要:本文使用STAR-CCM+仿真软件对Suboff主艇体模型的三维粘性流场进行数值研究,以获得具有较高精度的数值计算方法。通过将仿真结果和试验结果对比,分析不同的湍流模型和网格划分对计算结果的影响。结果表明:雷诺应力湍流模型仿真结果与试验结果最接近;当速度分别为5.92、10.00、11.84、13.92、16.00和17.99 kn时,相对误差小于3%的壁厚取值范围分别为:0.000 2~0.000 8 m、0.000 04~0.000 06 m、0.000 04~0.000 06 m、0.000 03~0.000 05 m、0.000 02~0.000 1 m、0.000 04~0.000 2 m,棱柱层总厚度取值范围为0.013~0.12 m,也可直接用公式计算。基于模拟分析结果,给出了AFF-1在改进网格划分方法后较为理想的数值计算结果。最后选择AFF-2模型验证了本文计算方法的准确性。A numerical investigation was conducted on the 3D viscous flow field around the Suboff bare hull model using STAR-CCM+simulation software to develop a high-precision numerical computation method.The influence of various turbulence models and grid divisions on the computational results was analyzed by comparing the simulation results with the experimental data.The simulation results of the Reynolds stress turbulence model are the closest to the experimental results.At the speeds of 5.92,10.00,11.84,13.92,16.00,and 17.99 kn,the value range of wall thickness that maintains a relative error of less than 3%is 0.0002~0.0008,0.00004~0.00006,0.00004~0.00006,0.00003~0.00005,0.00002~0.0001,and 0.00004~0.0002 m,respectively.The total thickness of the prismatic layer lies within the range of 0.013~0.12 m,which can also be determined using a direct formulaic calculation.The simulation analysis,an improved mesh division method for AFF-1,yielded more favorable numerical results.Finally,the AFF-2 model was selected to validate the accuracy of the computational method presented in this study.
