摘要：
In this paper, we studied the effects of D-sharp microchannel of two cross-section shapes of rectangle and ellipse with different aspect ratios on the focusing properties of the micro particles. The numerical simulation results show that elliptical cross section microchannel with aspect ratio of 2 has the best particle focusing effect. This is because the Dean drag force dominates the position of the particle; and the Dean vortex is stable in the elliptical shapemicrochannel, and the lateral flow velocity is the largest.
