使用Fluent软件,利用推板造波法和阻尼消波法建立数值波浪水池,用VOF方法追踪自由表面,采用RNG k-ε两方程湍流模型,基于动网格技术和用户自定义函数,提出一种模拟波浪中非流线型浮体运动的数值方法。应用该方法模拟波浪中二维非流线型浮体的大幅运动,将得到的运动响应曲线与实验值比较,分析误差产生原因,证明该方法的准确性,为浮力超常建造过程中的精度控制提供依据。
Fluent software is used to establish the numerical wave pool by using push plate wave method and damping wave elimination method. The free surface is tracked by VOF method. Based on the two-equation RNG k-ε turbulence model and based on moving grid technique and user-defined function, A Numerical Method for Simulating the Non - streamlined Floating Motion in Waves. This method was used to simulate the large-scale motion of the two-dimensional non-streamlined buoy in the wave. The obtained dynamic response curve was compared with the experimental data to analyze the cause of the error. The accuracy of the proposed method was proved to provide the basis for the precision control of buoyancy supernormal buildup.
