The Effect of Pumping in a Vertically Vibrating Pipe : Experimental Study on Flow Mechanism in a Pump

Abstract

Research was carried out on the pumping effect of a vibrating pipe system. Measurements were made on the relative displacement of the vibrating pipe and the valve, and the pressure and flow rate in the pumping system. Relevant time historical data are compared and details on the hydrodynamic mechanism of the pumping effect are discussed in this report. Analysis on the fundamental pumping energy for investigating the energy conversion between the vibrating pipe and fluid was also carried out and these results are introduced as well.
