| 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，定义了几个因次参数；获得了无因次回归方程。

| Abstract: | 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 preferable in ventilation of underground water powerhouses. |
