摘要
以十三陵水电站的交通洞为研究对象,运用数值模拟的方法,建立了交通洞数值计算模型.通过交通洞现场测试数据与数值模拟结果的对比,验证了模型的可靠性.采用实测验证后的计算模型对夏季工况下,十三陵水电站交通洞与室外进风的动态换热效果以及对应的节能潜力进行了研究,并分析了交通洞长度对其与室外进风换热效果的影响.十三陵水电站坝体廊道通风换热效果的研究,可为水电站地下厂房中通风、空调系统的节能设计和运行调节提供理论参考.
Numerical simulation method is used to study the dam tunnel of Shisanling Hydropower Station. The mathematical model of this tunnel is built, and the numerical simulation results by using this model are basically conforms with the data measured at the site. Using the validated calculation model, the dynamic heat transfer between dam tunnel and the outside air is studied, and the energy saving potential is predicted under the summer operational condition. In addition, the influence of tunnel length on heat transfer effect also is analyzed. The current results of dam tunnel ventilation of Shisanling Hydropower Station can provide a theory reference for energy saving design and regulation of underground powerhouse ventilation or air conditioning system.
