温度分层在大空间室内较为明显。本文首先对武汉某厂房室内垂直温度的分布情况进行了实测,并用CFD软件进行了模拟验证,比较发现零方程湍流模型的计算结果与实验数据吻合得很好。而后,分析了引起温度分层的因素,并总结得出了温度分层随位置和高度变化的规律。该结果可为大空间温度场理论研究提供参考。 Temperature stratification in the larger space is more obvious. In this paper, the distribution of indoor vertical temperature in a factory in Wuhan was measured. The CFD software was used to verify the simulation results. The calculated results of the zero-equation turbulence model were in good agreement with the experimental data. Then, the factors that cause temperature stratification are analyzed, and the rules of temperature stratification with position and altitude are summarized. The result can provide a reference for the theory of large space temperature field.
