Description

This paper concerns a piston pump without valves which consists of a piping system with a T-junction, two water tanks connected with both ends of the main pipe and a piston installed in the lateral pipe. Pump effect occurring in the system is examined theoretically and experimentally. The study is confined to the case that the time average flow in the main pipe is zero. The pump effect is a phenomenon that part of the energy corresponding to the time averages of kinetic energy in both of the main pipe is stored in one side of the tanks. Influences of system parameters on the pumping effect were clarified. The results obtained from a mathematical model proposed in this paper were found to be in good agreement with the experimental data.
