本文采用计算流体动力学（Computational Fluid Dynamics, CFD）方法，基于STAR-CCM+软件对一种新型首尾对称肥大型船舶回转性能进行数值预报。首先采用重叠网格和螺旋桨体积力相结合的方法，数值模拟该船舶在不同工况（静水、波浪）下的回转试验，重点分析了该船舶的回转半径和初始转首性能，其次对比了其在波浪条件下的回转性能。研究结果表明该船具有优良的回转能力，其回转半径较小，但在转向初期响应缓慢，表现出较差的初始转首性，并且其回转性能受到波浪的影响较小。研究结果为类似船型的设计优化提供重要参考，未来将致力于通过设计和操纵策略的调整，进一步提升该船型的操纵性能。
In this paper, a numerical prediction of the turning performance of a new type of bow-stern symmetric fat large ship is carried out using the Computational Fluid Dynamics (CFD) method based on STAR-CCM+ software. Firstly, the turning test of the ship under different working conditions (calm water and wave) is numerically simulated by combining the overlapping grid and the propeller volume force, focusing on the analysis of the turning radius and the initial bow turning performance of the ship, and then the turning performance under wave conditions is compared. The results show that the vessel has excellent turning capability with a small turning radius, but is slow to respond at the start of steering and has poor initial bow-turning performance, and its turning performance is less affected by waves. The results of the study provide an important reference for design optimisation of similar vessels, and the future will be devoted to further improving the manoeuvring performance of this vessel by adjusting the design and manoeuvring strategy.
