【摘要】 采用基于数值波浪水池技术的CFD方法,进行顶浪中三体船水动力布局优化研究,探索耐波性能优良、波浪增阻较低的水动力布局。文中研究了侧片体纵向位置变化对波浪中三体船水动力性能(运动响应与增阻)的影响,并与模型试验结果进行了比较,二者符合较好。研究结果表明,三体船侧片体纵向位置对其在波浪中的水动力性能有显著影响。更多还原

【Abstract】 Optimization of hydrodynamic configuration for a trimaran in head waves was carried out in this paper by CFD method based on the technique of numerical wave tank.The purpose of this research work is to search for the hydrodynamic configuration with high performance of seakeeping and low added resistance in waves.Research work on the effect of longitudinal placement variations of side hulls on the hydrodynamic performance in waves of a trimaran was carried in this paper.The numerical results were compared with the experimental data and show rather good agreement.The results indicate that the effect of longitudinal position of side hulls on hydrodynamic performance of the trimaran is remarkable.更多还原
