Pumping Effect in an Axially Vibrating Choke Nozzle : Pump Performance

抄録

A newly developed pumping system is presented. The pumping effect was experimentally obtained using a vibrating choke nozzle in a stationary liquid. The relation-ship between pump performance and the input vibration conditions was investigated. By the flow visualization of inflow and outflow bubbles, the flow mechanism in the actual pump operation was investigated. It has been confirmed that this pumping effect can be utilized in actual pump machinery.
