ダイアフラムポンプの脈動低減に関する研究 (非線形波動現象の数理とその応用)

Abstract

Discharge pulsation of a diaphragm pump is studied experimentally and numerically. The pulse occurs when the channel is blocked by the check ball to prevent the reverse flow. Propagation of the plus in an elastic tube is also investigated through the measurement of the pressure and the discharge, and is studied by numerical analysis. Numerical analysis show that the pressure waves propagate downstream, but the standing envelope of the waves appears because of the partially reflected waves.
