| 摘 要： | 核电厂常规岛汽轮机房通风设计一般采用的计算方法无法确定汽机房内的温度和速度分布，而采用Computational Fluid Dynamics(简称CFD)软件对其室内热环境进行模拟、分析和评价，可以直观地看到汽轮机房各区域温度的情况.同时，CFD方法可以方便地对方案进行反复调整分析以使厂房各点的温度达到设计要求。CFD精细的预测结果，能够为热车间的通风设计提供切实可行的设计策略和方案修正手段．采用CFD的设计方法能够挖掘通风系统的设计亮点，提供了可靠的设计手段。

| Abstract: | Conventional ventilation calculation methods and design scheme of nuclear power plant turbine room can not determine the distribution of temperature and velocity in turbine room. The distribution of temperature and velocity could be visually seen by the use of Computational Fluid Dynamics (CFD) software to simulate, analysis and evaluate turbine room indoor thermal environment . What's more, design scheme could be easily adjusted and analyzed to meet the temperature design requirements by CFD method. Fine predictions of CFD could provide practical design strategies and scheme correction means for the ventilation design of hot workshop. Design using CFD method could tap the highlights of the ventilation system, providing a reliable design tools. |
