Analysis of Blood Extraction from a Lancet Puncture

Kuriger R.J., Romanowicz B.F., CFD Research Corporation, US

A computational model was created utilizing the CFD-ACE+ software to model blood flow from a lancet puncture of the skin. A two-dimensional axisymmetric model was developed and the skin tissue was modeled as a porous [...]

CFD-based Optimization of Gas/Liquid Microreactors with Droplet and Bubble Transport

Hardt S., Pennemann H., Jiang F., Institute of Microtechnology Mainz, DE

Microreactors offer unique opportunities for the control of process parameters unparalleled by macroscopic equipment. A new gas/liquid microreactor is proposed allowing for fast mass transfer and small concentration gradients as well as a very narrow [...]

Gas Flow Simulation in a PECVD Reactor

da Silva A.N.R., Morimoto N.I., LSI – EPUSP, BR

In this work are presented the gas flo simulation in a hand made PECVD-TEOS reactor. We used the FLOTRAN-CFD code of the ANSYS simulator to predict the velocity and temperature curves in the reactor. The [...]

System Model for a Novel No Moving Parts Diffuser Valve Based Diaphragm Actuated Micro Pump

Banerjee D., Yano K., Bart S.F., Coventor, US

Analytical results for oscillating flow in a channel indicate regions of high shear stress close to the wall along with the flow reversal in the central portion of the flow at certain frequencies of actuation. [...]

Modeling and Validation of Flow-Structure Interactions in Passive Micro Valves

Oosterbroek R.E., Schlautmann S., Berenschot J.W., Lammerink T.S.J., van den Berg A., Elwenspoek M.C., University of TWente, NL

This paper reports the modeling of the stationary flow-structure interaction of different types of micro check valves. Mathematical indirect, domain coupled and decoupled, finite element models as well as analytical approximations are made. The obtained [...]
