【英文篇名】 Research of ceiling air supply in underground water powerhouses 【作者中文名】 付祥钊; 【作者英文名】 By Fu Xiongzhao; 【作者单位】 重庆建筑大学; 【文献出处】 暖通空调, HV 地下主厂房; 气流组织; 相似模型试验; 【英文关键词】 underground water powerhouse; air distribution; scale model test; 【摘要】 水电站地下主厂房的送风量很大，采用顶送风方式可避免大量占用有用空间。用相似模型试验研究了这一送风方式，分析了送风口数目、位置、尺寸及送风风速对工作区温度和风速的影响，定义了几个无因次参数；获得了无固次回归方程。这些方程可广泛用于工程实践。研究结果表明，顶送风的效果是满意的。建议水电站地下主厂房采用顶逆风方式。 【英文摘要】 The volume of supply air to an underground water powerhouse is very large. Supplying air from the ceiling can save much space in the house. Studies it with scale model tests. Investigates the effects of different number, location and size of inlets and velocity of supply air on the temperature and velocity in occupied zone. Defines a few of dimensionless variables and derives the dimensionless regression equations that can be used in practice. The results of the research show that the ceiling air supply is...
