On the Motion of a Bubble through Microchannel Contractions

Chio H., Jensen M.J., Wang X., Bruus H., Attinger D., Columbia University, US

We present the first transient pressure measurements and high-speed visualizations of a gas bubble passing through liquid-filled microchannel contractions. Results are compared with a simple theoretical model taking into account the Young-Laplace pressure drop, the [...]

Simulation of (Self-) Priming in Capillary Systems Using Lumped Models

Sesterhenn M., Mellmann J., Löhr M., Stierle B., Strobelt T., Sandmaier H., University of Stuttgart, DE

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 [...]
