中文摘要：

本文以武汉某高大空间工业厂房的地道通风系统为研究对象,根据热压原理建立了地道自然通风的计算流体动力学（Computational Fluid Dynamics,CFD）预测模型,根据现场实测数据验证了该预测模型的准确性基本符合要求。利用该CFD预测模型研究了地道长度和竖井高度对地道通风量、地道出口处空气温度及工作区空气平均温度的影响规律,得到地道长度和竖井高度的最优值分别为200 m和3 m。本文的研究结果为高大空间工业厂房地道通风系统的优化设计提供了理论支持。

英文摘要：

This paper takes the tunnel ventilation system of a certain industrial factory with high and large volume in Wuhan City as the research object. A CFD prediction model for natural ventilation in the tunnel is built based on the thermal pressure theory. The accuracy of the prediction model is proved with satisfactory results according to the site survey data. With the help of the CFD prediction model,the paper studies the influence pattern of the tunnel length and shaft height on the tunnel ventilation amount,tunnel exit air temperature,and the working area average air temperature. The results show that the optimized values for the tunnel length and shaft height are respectively200 m and 3m. The paper thus provides theoretical support for the optimized design of tunnel ventilation system of the industrial factory with high and large volume.
