为了设计具有更好阻力和推进性能的船体，必须了解船舶周围的流动特性，如波浪和尾流的发展。详细描述局部流动特性的实验数据对于验证计算流体动力学（CFD）代码的物理和数值建模是非常宝贵的，CFD代码最近作为船体形状评估的有效工具而受到关注。本文描述了KRISO 138,000 m3带螺旋桨和舵的LNG船模型在拖曳水池中测量的速度和波浪剖面。螺旋桨和方向舵对尾流和波型的影响被清楚地识别出来。本文所包含的结果可以提供一个机会，探索在自航条件下的模型船周围的综合流动现象，并可以添加到国际拖船会议的CFD验证基准数据作为以前的KCS和KVLCC的情况。
For the design of hull forms with better resistance and propulsive performance, it is essential to understand flow characteristics, such as wave and wake development, around a ship. Experimental data detailing the local flow characteristics are invaluable for the validation of the physical and numerical modeling of computational fluid dynamics (CFD) codes, which are recently gaining attention as efficient tools for hull form evaluation. This paper describes velocity and wave profiles measured in the towing tank for the KRISO 138,000 m3LNG carrier model with propeller and rudder. The effects of propeller and rudder on the wake and wave profiles in the stern region are clearly identified. The results contained in this paper can provide an opportunity to explore integrated flow phenomena around a model ship in the self-propelled condition, and can be added to the International Towing Tank Conference benchmark data for CFD validation as the previous KCS and KVLCC cases.
