摘要
以某一特定穿浪双体船为研究对象,基于计算机流体动力(CFD)仿真软件,模拟了船体在不同海况和航速下的运动响应,通过对缩减船的纵向运动程度的分析,初步确定了T型水翼的安装位置为距离船艏9-39 m处,并对不同安装位置和不同立柱高度的T型水翼进行了水动力仿真,依据T型水翼的减摇原理以及对其在不同条件下升力系数曲线的分析,得到了受船体约束的T型水翼的最佳安装位置为距离船艏29 m及最佳立柱高度为2.55 m.结果表明:与船体相适配的T型水翼减摇效果显著,有效地改善了穿浪双体船的耐波性能.
Based on computer fluid dynamic(CFD) simulation software,motion response of a wave piercing catamaran(WPC) was simulated in different sea states(SSN) and speeds.The T-foil's preliminary installation scope was 9-39 m away from the bow through analyzing the longitudinal motion of the reduced ship model,and different installation locations and strut's heights of T-foil were simulated and studied by hydrodynamic simulation software.The optimum installation location was 29 m away from the bow and the optimum strut's height was 2.55 m based on the anti-heaving and pitching principle and the analysis of lift coefficient curves in different situations.Results show that the fitted T-foil is advantaged to the heave and pitch reduction,and the seakeeping of WPC is improved effectively.
