Abstract

This paper presents an experimental investigation of the effect of velocity profile on the particle separation. Electroosmosis flow (EOF) and pressure driven flow are combined to adjust the velocity profile arbitrarily. Compared with the previous studies on the interface position, this paper finds out that the velocity profile contributes more significantly to the separation performance. In addition, the experimental results show that the velocity profile with higher velocity gradient has better separation performance. The whole design features simple manipulation, high stability and high separation performance, making it promising for particle separation applications.
