摘要

船舶的操纵特性是一种复杂的现象，包括保持稳定航向和转弯能力。目前还没有简单的方法来评估船舶在这些方面的性能。此外，与这些现象相关的流动模式也很复杂，经常与其他因素结合在一起。本研究的目的是评估一艘 37000 吨载重量的化学品油轮的航向保持和转向性能。根据稳定性标准对航向保持进行评估，同时采用经验关系和数值模拟，利用经验方法和计算流体动力学（CFD）方法的流体动力学导数对转弯半径进行分析，然后与实际海试数据进行比较。

A comparative analysis of course keeping and turning circle for a 37000 tdw chemical tanker

The maneuvering characteristics of ships represent complex phenomena, which includes their capacity for both maintaining a steady course and turning ability. There are no simple methods for evaluating a ship's performance in these aspects. Furthermore, the flow patterns connected to these phenomena are complex and frequently coupled with other factors. The purpose of this study is to evaluate the course keeping and turning performance for a 37000 tdw chemical tanker. Course-keeping is evaluated based on stability criteria, while empirical relations and numerical simulations using hydrodynamic derivatives from both empirical and computational fluid dynamics (CFD) methods are employed to analyse the turning circle and then compared with data from actual sea trials.
