Paper Title:
Inertial Flow Phenomenon Analysis on Piezoelectric Pump
  Abstract

The author finds that there is outflow during piezoelectric pump sucking process, and a dynamic model combined with hydrodynamics and mechanical vibration is presented for the anlysis of piezoelectric pump sucking process phenomenon. The model is utilized to study the reason of sucking process outflow and the effect of the driving frequency, outlet valve rigidity, the load in inlet and outlet on the sucking process outflow. The result turns out that the flow inertia is the cause of sucking process outflow; the inertial flow also exists during draining process as the sucking process; increasing driving frequency, or outlet valve rigidity, the inertial flow decreases, increasing the load in inlet and outlet has the same effect. The research makes it clear that the pump output flow should include two parts, bulk flow and inertial flow, which will provide theory reference for the precise flow control of piezoelectric pump.
