Investigation of Double-Chamber Series Valveless Micropump : An Analytical Approach

Abstract

We describe an analytical study of the characteristics of a double-chamber series valveless micropump using a one-dimensional non-linear model. We derive a closed-form expression for relationship between the mean volume flux, pressure difference and measurable characteristics of the pump. To first order, the results show the linear decrease of the volume flux with the pressure difference, which is consistent with other types of valveless pump configurations.
