Combined effects of pump and capillary pressures for the filling of microchannel networks: the difficulty of synchronization

Berthier J., Diakite M.L., CEA-Leti (University Grenoble Alpes), FR

In this work, we first propose a model for the filling of a capillary tube driven by a pressure pump. It is shown that the filling time depends not only on the pump pressure but [...]

Attenuation of Disturbances Using Packed Bed of Nanoparticles

Asif M., Ali S.S., Hameed B.H., King Saud University, SA

The attenuation of disturbances and shocks is quite important as well as challenging task in a variety of situations. In the present work, the attenuation of disturbance through a packed bed of ultrafine nano-powder that [...]

Optimal Shape Design of Pressure-Driven Curved Micro Channels with Hydrophilic and Hydrophobic Walls

Lim S., Choi H., Seoul National University, KR

In microfluidic applications such as LOC, 90-deg. and 180-deg. curved channels are frequently used to supply long flow passage in a compact volume. In most curved channels, the part connecting two straight channels is made [...]

Prediction of the Pressure Drop Through Micromachined Particle Filters

Yang J.M., Yang X., Yang J.M., Yang X., Ho C-M., Tai Y-C., UCLA, US

Micro-filters are fabricated using MEMS technology, and both measurements and numerical calculations are carried out in order to estimate the power requirement in a micron-size particle collection process using the micro-filter. In order to numerically [...]
