Abstract: One experimental system with high accuracy is established for unsteady flows of open-channel, which can generate continuously unsteady flows through the rotation speed of water pump controlled by computer and transducer. The discharge and the change of water level are monitored in real time by electromagnetic flow meter and ultrasonic water level recorder; and the flow field measurement are carried out by particle imagine velocity (PIV). It is showed that the experiment system can not only generate unstable flows continuously and stably, but also promote the experimental measures of unsteady flows of open-channel.

Key words: unsteady flows of open channel , PIV( Particle Imagine Velocity) , experimental system ;

摘要: 建立了一套高精度的明渠非恒定流试验系统,通过计算机及变频器控制水泵转速产生非恒定流过程,由电磁 流量计、超声水位计实时监测流量和水位变化过程,并通过PIV流场仪进行流场测量。该系统不但能生成连续、稳 定的周期性非恒定流过程,很大程度改进了明渠非恒定流的试验手段。
