| 摘 要： | 文章用RANSE求解器计算在自由面上带舭龙骨二维柱体的横摇水动力系数(附加惯量和阻尼).采用有限体积法(VOF)和两相流技术在时间域内求解柱体横摇强迫振荡所扰动的带自由面粘性流场.由柱体所受到的横摇水动力矩的时间历程导出横摇水动力系数.文中所给算例与已公开发表的试验结果吻合令人满意.

| Abstract: | An RANS solver is used to predict roll hydrodynamic coefficients(added inertia moment and damping)of a two-dimensional section with/without bilge keels on the free surface.The viscous flow field disturbed by the forced roll motion is solved in time domain with VOF and two-phases flow approach.The roll hydrodynamic coefficients are derived from time histories of the roll hydrodynamic moments.The results are compared with published model test measurements and a fairly good agreement was found. |
