Acoustic streaming of a sharp edge
The Journal of the Acoustical Society of America, 2014Anomalous acoustic streaming is observed emanating from sharp edges of solid bodies that are vibrating in fluids. The streaming velocities can be orders of magnitude higher than expected from the Rayleigh streaming at similar amplitudes of vibration.

Microfluidic viscometer by acoustic streaming transducers
Lab on a Chip, 2023We introduce μVAST, a high-throughput acoustic microstreaming platform using second-order microstreaming to induce fluid transport and measure the viscosity of 16 samples, automating process flows in drug development, materials manufacturing and production.

Redshift of acoustic waves in acoustic streaming
Physical Review E, 2003Redshift, namely, the frequency decline in the frequency spectrum of an acoustic wave in water, was observed by measuring the frequency spectrum of acoustic streaming in a standing wave field. We desire that relations of the energy epsilon and momentum mu of acoustic waves analogous to those under quantum conditions hold, that is, epsilon =n(p)h(omega),

There is a general formulation by Nyborg that accounts for the streaming inside the viscous boundary layer on a solid surface in the presence of a sound wave [W. L. Nyborg, J. Acoust. Soc. Am. 30, 329 (1958)]. Using the streaming velocity at the edge of the viscous layer from Nyborg’s theory as a slip boundary condition, the streaming pattern at large ...

Acoustic Streaming in Ovarian Cysts
Journal of Ultrasound in Medicine, 2005The purpose of this study was to investigate the hypothesis that endometriomas do not show acoustic streaming and then to quantify the streaming velocity of the particles within ovarian cysts that do show acoustic streaming.Ovarian cysts greater than 2 cm in diameter, with internal echoes seen on B-mode sonography, were prospectively evaluated for the ...

Acoustic streaming: An in vitro study
Ultrasound in Medicine & Biology, 2003The aims of this study were, first, to determine if cyst size and cyst-to-transducer distance have an impact upon acoustic streaming and, second, to investigate the effect of cyst content viscosity on acoustic streaming using an artificial ovarian cyst model. Artificial ovarian cysts were constructed and suspended in a tissue-mimicking bath.

We discuss two types of acoustic streaming, namely the ``quartz wind'' and Rayleigh streaming. Both are associated with flows that are dominated by their fluctuating components, and owe their origin to the action of Reynolds stresses. In the former, these stresses arise within the main body of the fluid when an ultrasonic beam propagates into it; in ...
