标准方程模型、RNG方程模型和零方程模型是通风空调工程上最为常用的湍流方程模型。本文对三种湍流模型进行了介绍，并用三者对百叶风口空气射流进行了模拟。模拟结果表明，与其它两种方程模型相比，采用标准方程模型，无论是轴心速度衰减还是断面速度分布，与实测最为吻合，而采用零方程模型与实测差别较大。

Standard two equation model, RNG two equation model and zero equation model are commonly used in HVAC engineering . In this paper, three turbulence models are introduced, and deflection grille air jets are simula-ted with them. Results show that compared with the other two equation model, using the standard equation model, whether in axial velocity attenuation or in fracture surface velocity distribution, using standard two equation, the simulation is the closest with the measured. While, using of zero equation model , the simulation have great differ-ence from the actual.
