【摘要】 与传统的拖曳水池试验相比,应用循环水槽开展平面运动机构试验,可通过长时间的连续测量获得稳定、精细的试验结果,同时也可进行可视化观测测量。本研究应用上海交通大学新建的循环水槽试验装置,以大型油轮KVLCC2模型为研究对象,对其进行了多个工况下的斜航和纯横荡、纯艏摇试验,测量了水动力数据。此外,采用通用CFD软件,对KVLCC2模型在相同工况下的斜航试验进行了数值验证,将计算得到的水动力、力矩与实验数据进行对比。研究结果证明循环水槽平面运动机构试验结果可信,具有较高的实用性,相应CFD模拟计算具备一定的工程实用精度。更多还原

【Abstract】 The captive model test using a planar motion mechanism(PMM) in the circulating water channel(CWC) newly built in Shanghai Jiaotong University provided steady and reliable data.This article describes the analysis and results of oblique towing test,pure swaying test and pure yawing test using the benchmark ship KVLCC2 with a series of working conditions, in which hydrodynamic derivatives were obtained.Moreover,the numerical simulation of the oblique towing test in the same condition was performed with a general-purpose computational fluid dynamics(CFD) package and hydrodynamic forces and moments acting on the model were obtained and compared with the test data.The study demonstrates the high reliability and practicability for PMM test in CWC and that the corresponding CFD simulation is a practical approach for engineering.更多还原
