Determination of the complex-valued elastic moduli of polymers by electrical impedance spectroscopy for ultrasound applications
William N. Bodé, Fabian Lickert, Per Augustsson +1
A method is presented for the determination of complex-valued compression and shear elastic moduli of polymers for ultrasound applications. The resulting values, which are scarcely…
Fast microscale acoustic streaming driven by a temperature-gradient-induced non-dissipative acoustic body force
Wei Qiu, Jonas Helboe Joergensen, Enrico Corato +2
We study acoustic streaming in liquids driven by a non-dissipative acoustic body force created by light-induced temperature gradients. This thermoacoustic streaming produces a velo…
Particle-size-dependent acoustophoretic motion and depletion of micro- and nanoparticles at long time scales
Wei Qiu, Henrik Bruus, Per Augustsson
We present three-dimensional measurements of size-dependent acoustophoretic motion of microparticles with diameters from 4.8 um down to 0.5 um suspended in either homogeneous or in…
Characterization of Acoustic Streaming in Gradients of Density and Compressibility
Wei Qiu, Jonas T. Karlsen, Henrik Bruus +1
Suppression of boundary-driven Rayleigh streaming has recently been demonstrated for fluids of spatial inhomogeneity in density and compressibility owing to the competition between…
Acoustic streaming and its suppression in inhomogeneous fluids
Jonas T. Karlsen, Wei Qiu, Per Augustsson +1
We present a theoretical and experimental study of boundary-driven acoustic streaming in an inhomogeneous fluid with variations in density and compressibility. In a homogeneous flu…
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…
