摘　　要：在发生CAP1400非能动核电厂事故1个月后,仅通过非能动空气流道可实现安全壳的冷却。设计上,要求空气流道的气动特性尽可能不受外界环境风的影响。本文应用STAR-CCM+软件对大型先进非能动核电厂CAP1400实际1∶1模型进行计算流体力学(Computational Fluid Dynamics,简称CFD)分析,研究环境风速、风向、温度等因素对空气流动特性的影响,分析结果表明CAP1400具有风的中立特性。During long-term period following an accident f or passive nuclear power plant, the containment cooling depends on passive air flow path. In design the flow characteristic in air flow path should be not sensitive to the environment wind. In this paper,the 1∶1 CFD（Computational Fluid Dynamics）model for CAP1400 which is a large advanced passive nuclear power plant is established with STAR-CCM＋,and then different factors such as wind velocity,wind direction and temperature are studied. Finally,the CAP1400 passive air flow path wind-neutrality characteristic is obtained.
