By utilizing unidirectional air servo system, fluid flow can be regulated within microchannels. The operation of servo system is controlled with multiple nozzles. Pressure variations lead to two fundamental operational modes: 'suction' and 'exclusion' in channels. Three-dimensional finite volume simulations are tested to demonstrate that operation mechanism for suction is via the generation of a reverse airflow, while exclusion is obtained without the reverse airflow. |  | View paper | | ISBN: | 0-9666135-7-0 |
