| | Clogging Pressures of Bubbles in Microchannel Contractions: Theory and Experiments | | Authors: | M.J. Jensen, X. Wang, D. Attinger and H. Bruus | | Affilation: | Mikroelektronik Centret, DTU, DK | | Pages: | 267 - 270 | | Keywords: | microchannel, contraction, bubble, clogging | | Abstract: | We present a theoretical, numerical, and experimental study of bubbles passing through a microchannel contraction. A certain pressure, the so-called clogging pressure, is needed to push a bubble through a microchannel contraction. We present the first experimental results on such systems and compare them to results from a theoretical model first presented at NanoTech 2003 (M. J. Jensen et al., Proc. vol. 1, p. 258-261). The experiments and theory are seen to be in quite good agreement and we give possible explanations for some of the discrepancies. | | ISBN: | 0-9728422-7-6 |
