| 摘 要： | 采用多块搭接结构化O型和H型网格对某载人潜器周围控制域进行网格离散,分别采用四种不同的湍流模型,并改变自由来流湍流强度的设置,对潜器周围绕流场进行数值模拟,得到了适于对潜器周围绕流场进行数值模拟的方法,获得较可靠的阻力等计算结果.将阻力计算结果与试验值进行对比,得出采用不同湍流模型进行数值计算时自由来流湍流强度的改变对于计算结果的影响.分析得出适于潜器阻力计算的湍流模型以及相应自由来流湍流强度的取值,为潜器的阻力预报提供了可行的数值计算方法,为潜器的阻力性能优化奠定了基础. |

| Abstract: | The flows of a manned submersible were numerically calculated for analyzing the drag performance of the submersible.The control volume of that submersible was divided into multi-blocks,and each block was meshed with O and H structured grids.With the change of turbulence intensity of free stream at the inlet of the domain,the flow around the submersible was simulated with four different turbulence models.The drags of the submersible calculated with the schemes of above combinations were compared with the cor... |
| Keywords: | manned submersible drag multi-block structured grids turbulence model turbulence intensity of free stream |
