Abstract

Previously, a compressible gas flow model was proposed, which couples microvalve structural parameters to gas parameters and flow boundary conditions, and which explained the behavior of compressible flow over a large range of conditions. However, only a limited set of data, from a single orifice for the valve seat, was used to substantiate the model. Multiple-hole or large-periphery valve seat structures were not measured. In this work, the proposed comprehensive compressible gas flow model for microvalves is confirmed using measurements of flow through multi-hole valve seat structures in microvalves.
