Numerical Calculation and Results Analysis for the Temperature of Underground Transformer Conveyance Tunnel in a Hydropower Station

根据现场实测和理论计算,建立了最大程度可靠而适于数值模拟的物理和数学模型,对地下隧洞内空气的流动换热利用FLUENT软件进行模拟;并对比模拟结果及实测数据;在此基础上分析隧洞尺寸、洞室进深、空气流速、壁面温度等对空气流动换热过程的影响,及其对最终隧道出口温度的影响。

The suitable physical and mathematics model were set up by the data from the field test and theory calculation and a simulation on the process of hear transfer during the air flowing in the tunnel using the computer was carried out. This paper compared the simulation results from the computer using FLUENT software with the data from the field test. Based this, the figuration and the depth of the tunnel, the velocity of the air, the temperature of the tunnel wall, how those parameters can affect the process of hear transfer during the air flowing in the tunnel are delt with.
