琅琊山水电站地下主厂房气流组织研究
Air distribution in underground main workshop of Langya Mountain Hydroelectric Power Station
摘要：
在不同的送风量、送风速度、送风温度、风口个数条件下，对琅琊山抽水蓄能电站主厂房顶拱送风方式进行了热态相似模型试验研究，得到了大量数据，对比国内二滩、小湾、龙滩等巨型水电站采用的顶拱均匀送风方案，针对琅琊山电站主厂房机电设备布置特殊性，提出适合该电站主厂房的顶拱非均匀送风方案。

Abstract：
Based on the experimental research on the thermal state simulation model of the station, mainly focus on the different manners of vault air supply, such as different quantity, velocity and temperature of air supply and different quantity of air outlet, obtains a great deal of experimental data. Compared with the successfully used vault symmetrical air supply manner in such famous great hydroelectric power stations as Ertan, Xiaowan and Longtan, with the particularity of equipment arrangement in this project, develops the vault asymmetrical air supply manner suitable for the power station.
