Comparison between V2F model and other turbulent models in simulation of indoor air flow
摘要：
介绍了V2F模型的表达式。对Annex 20算例进行了模拟计算，将V2F模型、雷诺应力模型、标准Kε模型、低雷诺数Kε模型、RNG Kε模型的模拟结果与其他研究者的实验结果进行了比较。结果表明，V2F模型在模拟室内空气流动中优于其他湍流模型。

Abstract：
Presents the expression of V2F model. Taking the Annex 20 case as an example, simulates indoor air flow using several different turbulent models including V2F, Reynolds stress, standard Kε, low Reynolds Kε and RNG Kε models. Compares the simulation results with experimental results obtained by other researchers. The results show that V2F model should be used prior to other turbulent models due to its good agreement with the experimental results.
