Acoustic Tweezing and Patterning of Concentration Fields in Microfluidics
Jonas T. Karlsen, Henrik Bruus
We demonstrate theoretically that acoustic forces acting on inhomogeneous fluids can be used to pattern and manipulate solute concentration fields into spatio-temporally controllab…
Performance study of acoustophoretic microfluidic silicon-glass devices by characterization of material- and geometry-dependent frequency spectra
Fabio Garofalo, Thomas Laurell, Henrik Bruus
The mechanical and electrical response of acoustophoretic microfluidic devices attached to an ac-voltage-driven piezoelectric transducer is studied by means of numerical simulation…
Modeling of microdevices for SAW-based acoustophoresis --- a study of boundary conditions
Nils Refstrup Skov, Henrik Bruus
We present a finite-element method modeling of acoustophoretic devices consisting of a single, long, straight, water-filled microchannel surrounded by an elastic wall of either bor…
The acoustic force density acting on inhomogeneous fluids in acoustic fields
Jonas T. Karlsen, Per Augustsson, Henrik Bruus
We present a theory for the acoustic force density acting on inhomogeneous fluids in acoustic fields on time scales that are slow compared to the acoustic oscillation period. The a…
