摘　　要：采用基于非结构化网格方法对神光Ⅲ装置靶场中间层室内空气流动进行了数值建模。分别应用基于RANS方法的Standard k-ε模型、RNG k-ε模型和SST k-ω模型,进行了数值模拟和分析。结果表明三种模型均能满足工程计算精度需求,采用RNGk-ε模型和SSTk-ω模型的模拟结果基本一致,二者的结果优于标准k-ε模型。A numerical model of SG- Ⅲ facility target area middle-floor was established with unstructured mesh- ed method for indoor air flow simulation. Three turbulence models based on RANS named standard k-ε model, RNG k-ε model and SSTk-ωmodel were respectively applied in calculation and analysis. It was shown that three models could satisfy the precision of engineering calculation and RNG k-ω model and SSTk-ωmodel achieved better consistency results. The results are better than the one of the standard k-ε model.
