Single burst acoustic streaming
AIP Conference Proceedings, 2000A new type of acoustic streaming is reported. It was first observed near a needle hydrophone while mapping the sound field of a focusing ultrasound transducer, when it resulted in unstable amplitude measurements of the field. The streaming was subsequently detected with tracer dye injected in the water near the needle probe.

The Journal of the Acoustical Society of America
In recent years, the need for accurate analysis of acoustic streaming has become urgent, as classical methods fail to quantify flows generated by acoustic waves beyond a few hundred kHz. This problem, identified since Lighthill’s seminal 1978 namesake publication, remains unresolved.

Acoustic streaming near Albunex spheres
The Journal of the Acoustical Society of America, 1998Acoustic streaming near bubbles in an external standing-wave sound field has been an interesting research topic for decades. It was relatively difficult to visualize the acoustic streaming pattern experimentally, especially for small bubbles due to the instability of the bubbles and difficulties associated with the optical technique.

Acoustic streaming in helium-II
Physica B+C, 1981Abstract The first quantitative measurements of acoustic streaming velocity in helium-II as a function of sound intensity and temperature are presented. Comparison with theoretical calculations to second order shows detailed agreement in the temperature range examined, 1.4 K ≤ T ≤ 2.0 K.

Acoustic Bubbles, Acoustic Streaming, and Cavitation Microstreaming
2015The phenomena of acoustic streaming and cavitation microstreaming can seem very complex, but underpinning them are fundamental concepts of fluid dynamics that are common to many similar systems. In this chapter, key aspects of fluid dynamics leading to bubble acoustics, acoustic streaming, and microstreaming are outlined.

Acoustic streaming in therapeutic ultrasound
The Journal of the Acoustical Society of America, 2012Wesley Nyborg’s contributions to a theoretical description of acoustic streaming were pioneering, rigorous, and so thorough that little additional work has been published. Acoustic streaming has had many applications in acoustics, especially medical acoustics, in which it is difficult to avoid.

Energy Balance in Acoustic Streaming
The Journal of the Acoustical Society of America, 1957The power required to maintain the Eckart type of acoustic streaming is calculated and found to be of sufficient magnitude to contribute measureably to the attenuation of large amplitude sound waves. A second problem has also been solved. When sound interacts with objects, streaming occurs due to the vorticity sources localized near the surface of the ...
