title = "Streaming direction and microparticle size effects in standing surface acoustic wave (SAW) devices",
abstract = "We report surprising and exciting physical understanding within microparticle acoustophoresis inside standing SAW-driven PDMS microchannels. The new insights are based on experimental measurements by high-resolution 3D particle tracking and numerical calculations employing a Lagrangian velocity-based formulation. In contradiction to existing literature, the acoustic streaming flows towards the actuation displacement node near the actuated substrate and its amplitude is smaller by an order of magnitude. The latter affects the transition size for which the particle motion is dominated by either the streaming-induced drag or the acoustic radiation force. These new findings will be crucial for further progress in SAW-driven microparticle acoustophoresis.",
