Use of COMSOL Multiphysics® - We model the fluid using the compressible Navier-Stokes equations in COMSOL Multiphysics® software. To circumvent the wide length and time scales associated with the typical SAW devices, we employed a perturbation approach resulting in first-and second-order equations (Figure 2), which are then successively

The validity as well as the applicable range of the long-wavelength calculation is evaluated with numerical simulations in Comsol Multiphysics®. The results are

The piezo is YZ LiNbO3, the PDMS structure is in the middle of the device and the fluid that flows in the channel is water. Acoustophoresis is an active method, where emphasis is on gentle, label-free, precise handling of cells based on their density and compressibility relative to the suspension medium as well as their size .

The model shows how the acoustopho-retic particle motion changes from being domi-nated by streaming-induced drag to being domi-nated by radiation forces as function of particle size, channel geometry, and material properties.
