大型邮轮开敞区域是乘客密集区域，对舒适性要求较高。本文运用雷诺时均方法探讨不同风向角下豪华邮轮开敞区域的流场特性，并用风洞实验对仿真结果进行验证，分析开敞区域流速、乘客受风角和烟囱烟气扩散情况，对邮轮开敞区域游客的舒适性情况进行评价。研究表明：从流速、乘客受风角以及脱涡情况考虑，60°风向角下，开敞区域流速最大，脱涡最明显，乘客舒适性较差；从烟囱烟气扩散考虑，180°风向角下，烟气会下洗到甲板上，严重影响乘客舒适性。研究结果可为邮轮开敞区域的布置设计提供指导。
The open area of large cruise ships is a passenger intensive area, which has high requirements for comfort. In this paper, the Reynolds time averaged method is used to discuss the flow field characteristics in the open area of luxury cruise ships under different wind angles, and the simulation results are verified by wind tunnel experiments. The flow velocity in the open area, the wind angle of passengers and the smoke diffusion in the chimney are analyzed, and the comfort of tourists in the open area of cruise ships is evaluated. The results show that considering the flow velocity, the wind angle of passengers and the vortex shedding, the flow velocity in the open area is the largest, the vortex shedding is the most obvious, and the comfort of passengers is poor under the wind angle of 60°. Considering the smoke diffusion from the chimney, the smoke will wash down to the deck at a 180 ° wind angle, seriously affecting the comfort of passengers. The research results can provide guidance for the layout design of open areas of cruise ships.
