resulting motion of a given particle is termed acoustophoresis, migration by sound. Experimental work on acoustophoresis has mainly dealt with the radiation force, primarily because this force dominates over the streaming-induced drag force for the studied aqueous suspensions of polymer particles or biological

It is thus thought interesting to embark on investigations into the cause and effects of the negative variation phenomenon. In this work, the positive and negative variations were first explained from the measurement sensitivity distribution perspective.

### COMSOL, Kongens Lyngby, Denmark Published in 2012 We have simulated the ultrasound-induced acoustophoretic motion of microparticles suspended in an aqueous solution. The full first-order thermoviscous acoustics equations have been implented on a rectangular microfluidic 2D domain excited with an ultrasound field tuned to resonance near 2 MHz.
