水电工程地下高大厂房通风空调气流组织及缩尺模型试验进展

Advancement about ventilation air distribution and reduced-scale model test for underground large plants in hydropower stations

介绍了水电站地下发电机主厂房通风气流组织的主要形式,包括分层空调、上(顶)送风、下送风和串联直流式通风。介绍了水电工程通风空调气流组织模型试验拟解决的关键技术点、模型试验理论和相似比例尺、模型设计问题、水电厂房火灾排烟模型试验,以及模型试验测量PIV技术,总结了国内典型水电站通风气流组织模型试验和火灾排烟模型试验情况。

Presents the main ventilation air distribution modes for the underground powerhouse in hydropower stations,including stratified air conditioning,up （or ceiling）supply,bottom supply and series uniflow type ventilation.Describes the key technical points,model test theory and similar scale,model design for the air distribution model test,and fire smoke extraction model test,as well as PIV measurement technique.Sums up the situations of ventilation air distribution model test and fire smoke extraction model test for the typical hydropower stations in China.
