摘要
提出一种部分计及自由面粘性效应及表面张力影响的完全非线性自由面边界条件,以该条件计算了方形系数Cb为0.8的Todd 60船型的非线性兴波问题,计算结果表明:非线性迭代的收敛性得到改善,兴波阻力被夸大的倾向有所改进。
A fully nonlinear free smface boundary condition, which partly includes the viscous effects and surface tension, is presented to improve the numerical calculation of wave-making problems for ships with high block coefficient. With the proposed method, the tendency of exaggerating the wave-making resistance and convergence in nonlinear iteration are improved.
