针对大型邮轮泳池晃荡的问题，基于CFD软件Fluent对不同形状泳池进行晃荡分析，研究影响泳池晃荡的因素。为获得准确结果，对邮轮水动力及泳池晃荡研究分别基于势流理论与粘流理论。研究结果表明：通过结合势流粘流理论可以高效准确的模拟泳池晃荡；3级海况下，对于矩形、圆形/椭圆以及棱形的泳池，横向宽度越大泳池晃荡引起的横向力越大，液面最大高度较高；纵横向过度越平缓引起横向力越小；相同海况下，棱形与椭圆形截面泳池晃荡幅度最小，可提高恶劣海况时泳池的舒适性。
Aiming at the sloshing problem of large cruise swimming pool, the sloshing of swimming pools with different shapes is analyzed based on CFD software Fluent, and the factors affecting the sloshing of swimming pool are studied. In order to obtain accurate results, potential flow theory and viscous flow theory are used for cruise hydrodynamic forces and swimming pool sloshing respectively. The results show that the sloshing of swimming pool can be simulated efficiently and accurately by combining the potential flow and viscous flow theory. For rectangular, circular and elliptical swimming pools, the greater the transverse width, the greater the transverse force caused by swimming pool sloshing, and the higher the maximum height of liquid level. Under the same sea conditions, the swimming pools with prismatic and elliptical sections have the smallest sloshing range, which can improve the comfort of the swimming pool in bad sea conditions.
