Characterization of acoustic streaming in water and aluminum melt during ultrasonic irradiation [PDF]

open access: yesUltrasonics Sonochemistry, 2021
It is well known that ultrasonic cavitation causes a steady flow termed acoustic streaming. In the present study, the velocity of acoustic streaming in water and molten aluminum is measured. The method is based on the measurement of oscillation frequency

Acoustic Streaming‐Induced Multimodal Locomotion of Bubble‐Based Microrobots [PDF]

open access: yesAdvanced Science, 2023
Acoustically‐driven bubbles at the micron scale can generate strong microstreaming flows in its surrounding fluidic medium. The tunable acoustic streaming strength of oscillating microbubbles and the diversity of the generated flow patterns enable the ...

A Numerical Investigation of the Mixing Performance in a Y-Junction Microchannel Induced by Acoustic Streaming [PDF]

open access: yesMicromachines, 2022
In this study, the mixing performance in a Y-junction microchannel with acoustic streaming was investigated through numerical simulation. The acoustic streaming is created by inducing triangular structures at the junction and sidewalls regions.

Numerical Simulation of Boundary-Driven Acoustic Streaming in Microfluidic Channels with Circular Cross-Sections [PDF]

open access: yesMicromachines, 2020
While acoustic streaming patterns in microfluidic channels with rectangular cross-sections have been widely shown in the literature, boundary-driven streaming fields in non-rectangular channels have not been well studied. In this paper, a two-dimensional

Acoustic Streaming Generated by Sharp Edges: The Coupled Influences of Liquid Viscosity and Acoustic Frequency [PDF]

open access: yesMicromachines, 2020
Acoustic streaming can be generated around sharp structures, even when the acoustic wavelength is much larger than the vessel size. This sharp-edge streaming can be relatively intense, owing to the strongly focused inertial effect experienced by the ...

Remotely extinguishing flames through transient acoustic streaming using time reversal focusing of sound [PDF]

open access: yesScientific Reports
Acoustic waves are a possible reusable method to extinguish flames. Previous studies have placed the sound source near the flame or have used standing waves to reach large enough acoustic amplitudes to extinguish it.

Manipulations of micro/nanoparticles using gigahertz acoustic streaming tweezers

open access: yesNanotechnology and Precision Engineering, 2022
Contactless acoustic manipulation of micro/nanoscale particles has attracted considerable attention owing to its near independence of the physical and chemical properties of the targets, making it universally applicable to almost all biological systems ...
