Abstract

In modeling the acoustic properties of microfluidics driven by surface acoustic waves (SAW), polydimethylsiloxane (PDMS) is usually used as the microchannel material. In this paper, based on a standing surface acoustic wave (SSAW) driven acoutstophoresis chip, the physical field and particle motion behavior in the microchannel are studied through numerical simulation. The major work includes: (a) the distribution of the acoustic pressure field in the microchannel; (b) the dominant behavior change of the drag force and the acoustic radiation force in the acoustic pressure field, which causes the trajectory change of the polystyrene particles. Based on the lossy-wall boundary conditions, it is shown that the model can simulate the acoustic flow and particle movement caused by leaky SAW in the microchannel. The obtained findings can also provide some suggestions for SAW device design and optimization.
