摘要
基于计算流体动力学(CFD)和结构化网格,应用通用软件FLUENT数值求解不可压缩RANS方程.采用定常旋转坐标系,对在Re=6.5×106不同漂角条件下预报潜艇做单平面回转运动的水动力.对比试验数据表明,力和力矩预报精度误差在工程允许误差范围内,符合工程实用条件.
Based on the CFD method and structured grid,general software FLUENT was used to solve the incompressible RANS equations. In a steady rotating coordinate system,the hydrodynamic force in the case of Re = 6. 5 × 10^6 and different drift angles was predicted for the submarine under plain surface. A comparison between the calculation results and experimental data indicates that the prediction accuracy error of hydrodynamic force and moment is within the engineering error range,which proves the satisfaction of engineering requirement.
