采用4种不同低雷诺数k-ε湍流模型,包括Abid模型、Launder-Sharma模型、Abe-Kondoh-Nagano模型和Chang-Hsieh-Chen模型,对矩形房间内空气流动的速度特性和湍流强度进行了数值研究.数值计算结果与实验数据吻合较好,4种低雷诺数k-ε湍流模型均能模拟室内空气的流动特性,其中Launder-Sharma k-ε模型能更好的预测速度特性,而其他3种模型能较好的预测湍流强度. Four different low Reynolds number k-ε turbulence models, including Abid model, Launder-Sharma model, Abe-Kondoh-Nagano model and Chang-Hsieh-Chen model, were used to investigate the velocity characteristics and turbulence intensity The numerical results agree well with the experimental data. The four low Reynolds number k-ε turbulence models can simulate the indoor air flow characteristics. The Launder-Sharma k-ε model can predict the velocity characteristics better, while the other The three models can predict the turbulence intensity well.
