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…

Diving with microparticles in acoustic fields
Alvaro Marin, Massimiliano Rossi, Rune Barnkob +5
Sound can move particles. A good example of this phenomenon is the Chladni plate, in which an acoustic wave is induced in a metallic plate and particles migrate to the nodes of the…
