Impedances for design of microfluidic systems

摘要

System analysis is essential for accurate design of complex microfluidic systems. For in-stance, 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 anlaytical methods for channels of non-varying cross-section. The resistance and iertance calculated are 20
