| 摘 要： | 基于BANS方程结合VOF处理自由面,建立了自由船模拖曳的数值模拟方法,并用于数条水面船模阻力的数值计算.数值模拟结果与模型试验的比较表明:在全Fr范围内,阻力数值计算结果与模型试验相差2%～3%之内,较拘束模计算准确度大为提高;兴波计算结果同样有明显改善;船模姿态的计算结果与模型试验也比较接近.建议在进行中高速水面船自由面绕流问题的数值计算时,使用自由模方法模拟.

| Abstract: | Numerical simulation of free ship model towed in still water is carried out in this paper by solv-ing RANSEs with VOF method for the treatment of free surface.The computed results of resistance,sink-age and trim for several surface ship models are compared with those of experiments and show quite good agreement.The prediction of resistance and wave profile is improved quite a lot as compared with that by restrained model simulation. |
