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…
