Pumping effect is examined theoretically and experimentally. The study is confined to the case that the time average flow in the main pipe is zero. The effect of resonance phenomena on the pump characteristics was clarified. The effect of system parameters on the pump characteristics was also clarified. The analytical results obtained from a mathematical model proposed in this paper were found to be good agreement with the experimental data., ・rights:日本機械学会 ・rights:本文データは学協会の許諾に基づきCiNiiから複製したものである ・relation:isVersionOf:http://ci.nii.ac.jp/naid/110002357732/}, pages = {831--836}, title = {Study of a Piston Pump without Valves : 2nd Report, Pumping Effect and Resonance in a Pipe-capacity-system with a T-junction}, volume = {28}, year = {1985} }
