水电站 HOBAS 压力管水锤波速和管壁糙度的测算

Determination of the Water-hammer Waves Propagation Speed and the Manning Factor n of HOBAS' Pressure Conduit in Hydroelectric Station

介绍了确定一种新型复合材料水电站压力引水管道─ＨＯＢＡＳ管的水锤波传递速度，以及管路内壁糙度的方法，试验结果表明，该种管材的水锤波传递速度不仅数值上约为钢管的１／２，而且随着内水压力的改变呈非线性变化。

A method to calculate the water-hammer waves propagation speed the manning of HOBAS, a new composite material pressure conduit applied in hydroelectric station,is supposed.The way to measure factor. The results of the test show that the water-hammer wave propagation speed of HOBAS is nearly 1/2 of that of penstock, and is nonlinear with the change of water pressure.
