摘要
System analysis is essential for accurate design of complex microfluidic systems. For instance, lumped-parameter system models of micropumps with no-moving-parts (NMP) valves need fluid elements that represent the separated, oscillating, laminar flow that occurs in these valves. No experimental or analytical method is currently available to determine the impedance of this type of flow. A numerical method for deriving NMP valve impedance has been developed, based on an extension of analytical methods for channels of non-varying cross-section. Thr resistance and inertance calculated are 20% lower than for a straight rectangular channel of equivalent length.
