Microstreaming and Its Role in Applications: A Mini-Review

Fluids, 2018
Acoustic streaming is the steady flow of a fluid that is caused by the propagation of sound through that fluid. The fluid flow in acoustic streaming is generated by a nonlinear, time-averaged effect that results from the spatial and temporal variations ...

Numerical analysis of water surface rising caused by underwater ultrasonic wave

Nihon Kikai Gakkai ronbunshu, 2022
When an underwater ultrasonic wave is emitted toward an air-water interface, the water surface rises and droplets are generated from the formed fountain.

Pressure-Driven Filling of Closed-End Microchannel: Realization of Comb-Shaped Transducers for Acoustofluidics [PDF]

, 2018
We demonstrate the complete filling of both deionized water (DI water) and liquid metal (eutectic gallium-indium, EGaIn) into closed-end microchannels driven by a constant pressure at the inlet.

Particle distributions in Lamb wave based acoustofluidics

Nanotechnology and Precision Engineering
Acoustic streaming enabled by a Lamb wave resonator (LWR) is efficient for particle trapping and enrichment in microfluidic channels. However, because Lamb waves combine the features of bulk acoustic waves and surface acoustic waves, the resulting ...
