Abstract:
In this paper, a toolbox of lumped models for simulating (self-)priming and emptying of complex capillary networks is presented. Each model is a kind of an all-in-one-model, that considers inertia, friction, gravitation and capillarity and has been implemented on a conventional, commercially available, mixed-signal system-level simulator. The toolbox contains fundamental microfluidic components which are lines with micromachined geometries, fittings, tees, dispensers and media transition elements. With these all-in-one-models it is now possible for the first time to layout complex capillary networks by simulating not only the dynamic behavior of filled systems but even the priming and emptying.
