Transient Filling Flow into Microchannels Considering Surface Tension

Kim D.S., Lee K-C, Lee S.S., Kwon T.H., Lee K-C, Lee S.S., Pohang University of Science and Technology, KR

In this paper, we investigated, both experimentally and numerically, transient “filling” flow into microchannels, which differs from completely “filled” flow in micro-channels. An experimental flow visualization system was devised to observe the characteristics of microchannel [...]

Numerical Modeling of Magnetic Field Flow Fractionation in Microchannels: A Two-fold Approach Using Particle Trajectories and Concentration

Berthier J., Pham P., Massé P., LETI, FR

Submicronic paramagnetic particles are currently used for biological applications like medical diagnostic [1]. Recently modeling of displacement of such particles has seen new developments like the calculation of the trajectory of a particle [2], or [...]

Coupled Fluid-Thermal-Structural Simulations in Microvalves and Microchannels

Athavale M.M., Yang H.Q., Przekwas A.J., CFD Research Corporation, US

This paper presents the results of high-fidelity, 3-D simulations of coupled flow, heat-transfer and structural mechanics simulations of microchannels, micropumps, microvalves, and time-accurate simulations of a microoscillator. In each of these cases, the simulated results [...]

A Surface Recombination Velocity Model for Liquid Flow in Microchannels

Zemel J.N., University of Pennsylvania and Scitefair International Inc, US

A number of years ago, Eyring introduced the free volume concept to explain why the viscosity of liquids decreased with increasing temperature while at the same time the density for most liquids also decreased (water [...]
