| 摘 要： | 利用标准两方程模型、低雷诺数NH模型,分别对室内空气流动换热的速度场、温度场、湍动能场进行了模拟,将计算结果与实验结果进行了对比分析.研究表明,低雷诺数NH模型能对室内空气流动换热的速度场、温度场、湍动能场进行较好的数值模拟,标准两方程模型的模拟的准确性较差.

| Abstract: | The author simulated the distributions of velocity, temperature and turbulent kinetic energy in indoor turbulent air flow and heat transfer with two kinds o f models-standard k-ε model and low-Reynolds-number NH model, which have been compared with the experimental data. The results obtained with NH model agreed well with the experimental data, and the precision of standard k-ε model was worse than the former. |
