基于CFD的规则波顺浪数值水池模拟

摘要

The regular following waves are reproduced by using CFD and a viscous numerical wave tank simulation technique. The waves are generated by wave boundary method and the free surface captured by Volume of Fluid (VOF) method. In this paper, the numerical simulation method of the regular waves in the traditional top waves is improved, and the simulation of different speed sailing in a certain following wave is carried out. Finally, the accuracy of the simulation is veri-fied by observing the shape of the waves generated in the simulator and comparing the experimental results with the Matlab outputs.%基于CFD（ Computational Fluid Dynamics）和粘性数值波浪水池技术，对顺浪航态的规则波波浪环境进行数值模拟，采用边界造波法进行波浪生成，VOF（Volume of Fluid）法模拟自由面。本文改进了传统的基于规则波的顶浪数值模拟方法，在特定波浪、不同航速条件下进行了顺浪航态的数值水池模拟。根据模拟呈现的动态效果，以及与Matlab仿真结果的对比，对试验的准确性进行验证。
