摘　　要：以某滨海任务舰为例,对主甲板层内空调区域气流组织分布进行评估。基于计算流体力学(CFD)方法,对舰内送风系统和各舱室内空调送、回风情况进行数值模拟。对各舱室关键区域速度场进行分析,重点关注餐厅、厨房、卫生间等负压舱室的气流量分布。结果显示,各舱室内正负压分布满足设计要求且有一定的气压裕度,表明该舰主甲板层内空调区域气流组织设计合理。Taking a coastal mission ship as an example,the air distribution in the air conditioning area of the main deck was evaluated.Based on the CFD method,a numerical simulation was carried out for the air supply system in the ship and the air supply and return condition in each cabin.The velocity field in the key area of each cabin was analyzed,focusing on the air flow distribution of the negative pressure compartment such as dining room,kitchen,toilet and so on.The results showed that the positive negative pressure distribution in each cabin meets the design requirements and has a certain margin,which indicates that the air flow distribution in the air conditioning area of the ship’s main deck layer is reasonable.
