潜艇主艇体模型水下水动力特性的数值分析
Numerical analysis of underwater hydrodynamic characteristics of submarine bare hull model
摘要
Abstract
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 0.000 2～0.000 8,0.000 04～0.000 06,0.000 04～0.000 06,0.000 03～0.000 05,0.000 02～0.000 1,and 0.000 04～0.000 2 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.关键词
