某极地船会议室的气流组织方案分析

Analysis on Airflow Distribution Plan of the Meeting Room on a Polar Vessel

对冬季和夏季工况下极地多用途集装箱船会议室内的气流分布情况进行分析。利用Flo EFD流体仿真分析软件,通过对冬季工况下会议室内的通风末端布置方案进行对比,以提高人员的热舒适度为方案选择目标,根据不同方案中的温度场、空气龄和速度场等气流组织指标的分布情况,定性分析得出方案B的各项优势。在夏季工况下对方案B进行仿真分析,突显在极地环境下会议室内的空气环境,为我国后续极地船舶会议室设计提供参考。

This paper analyzes the airflow distributions in the meeting room of a polar multi-purpose containership under winter and summer working conditions. The fluid simulation and analysis software FloEFD is used in selecting a proper scheme. When the comparisons of the ventilation terminal schemes for the meeting room under winter working condition were carried out on the basis of thermal comfort improvement, the advantages of scheme B became visible in the qualitative analysis regarding the airflow distribution indexes such as temperature field, air age and velocity field. Then Scheme B was further analyzed with the simulations under the summer working condition, where the emphasis is laid on the air environment of the meeting room under polar environment. This study provides reference for the meeting room design of subsequent polar vessels built in China.
