Abstract
The laminar motion of fluid in microchannels is the necessary criteria for integrated microfluidic system as lab-on-a-chip. Experiments were conducted to investigate laminar flow characteristics of dyed water through photoresist microchannels with square pillars. We found that the pillar dimensions on the channel surfaces have significant impact on the flow rate. The evaluated Reynolds number was less than unity in each microfluidic flow. The compatibility between the pillar sizes and corresponding air-water meniscus movement in microfluidic flow has been reported. [DOI: 10.1380/ejssnt.2009.330]
