Predictive flow rate distribution in the scale-up of capillary-based microfluidic system

Guo Chengchu;Ma Tao;Huang Jia;Chang Zhenqi;School of Nuclear Science and Technology,University of Science and Technology of China;  
In this paper,a capillary-based microfluidic control amplifying device was designed.The effect of capillary size,capillary length,fluid flow rate and fluid viscosity on the distribution of microfluidic flow was studied in detail.The results show that with the decrease of capillary inner diameter,the increase of capillary length,fluid flow rate and fluid viscosity,the fluid flow distribution uniformity is better,that is,the variation coefficient(CV)of fluid flow becomes smaller.The empirical formula describing the relationship between CV and its influence parameters is obtained.
