基于粘性流船舶数值波浪水池造波和消波方法研究

摘要

Shake of rocker panel was achieved by using of technology of dynamic mesh. Free surface of ship numerical wave tank was simulated through incompressible viscous fluid Navier-Stokes equation and vol-ume of fraction (VOF) method, adding to source term method in the momentum equation in order to wave damping. By using of CFD business software Fluent and its secondary development function, three-dimen-sional numerical wave tank model of regular wave based on physics wave-generating imitating method was established through turbulence model standard k-ε. The result shows that wave generated through physics wave-generating imitating method has the feature of high quality and stability.%　　利用动网格技术实现了造波板的摇动，通过不可压缩粘性流体的Navier-Stokes方程和流体体积法VOF (Volume of fraction)模拟了船舶数值波浪水池的自由表面，并结合湍流模型标准k-着，同时在动量方程中添加源项的方法实现阻尼消波，基于仿物理的摇板造波数值方法，采用CFD商业软件Fluent及其二次开发功能，建立了三维规则波数值波浪水池模型，通过结果分析可得，仿物理的摇板造波的质量高且稳定性好。
