摘要
基于CFD方法建立了数值波浪水池,模拟了规则波浪的生成传播,并对顶浪中航行船舶的运动进行了模拟计算研究。讨论了数值模拟中的波浪环境表达,验证了数值波浪水池中波浪的生成、传播与消波等,模拟计算了多个航速顶浪中航行Wigley-III船模的运动与波浪增阻。将计算结果与DUT(Delft University of Technology)的试验数据相比较,吻合良好。对比和研究表明,基于数值水池的数值模拟方法比试验更易实现和控制,能细致描述船舶周围的流场,在波浪中舰船水动力性能的分析与运动预报等方面具有广阔的应用前景。
Numerical simulation on a ship advancing with certain forward speeds in regular heading waves were carried out in the numerical wave tank （NWT）. Regular waves making and propagation were successfully simulated and verified in a reference coordinate system. Ship motions and added resistance of Wigley-III advancing in heading waves with different speeds were calculated respectively. A comparison of present results with corresponding experimental data from Delft University of Technology have been made, and it is shown that the results agree well. Compared with physical experimental method, present method has the virtues of easy controlled and realization with low cost. It is of great significance to the analysis and prediction of hydrodynamic performance of ship and marine floating structures in waves.
