Abstract

A design methodology for extracting component models for fluid dynamic devices is presented. The analysis uses Memcad’s suite of design tools to build the solid model and perform the analysis and post-analysis to extract the parametric variations of interest. In this paper, we demonstrate this capability by analyzing two types of no-moving-parts (NMP) valves used in micropumps: the diffuser type and the Tesla-type valves. The results indicate that the Tesla-type NMP valve has a higher pumping efficiency, and therefore a higher throughput, for the same Reynolds number flow, compared to the diffuser type valve. The parametric behavior reported by Memcad can then be used to generate a reduced-order model for system level simulations in a straightforward manner.
