Fluid flow modelling of a micro-valve

Abstract

This paper presents a fluid flow analytical model of a micro check valve based on an ortho-planar spring. The comparison with a coupled fluid-structure finite-element model shows that the analytical model gives results very close to the finite-element model (FEM). These models are then validated using flow rate measurements on valve prototypes.
