Advances in Micromanipulation Actuated by Vibration-Induced Acoustic Waves and Streaming Flow

open access: yesApplied Sciences, 2020
The use of vibration and acoustic characteristics for micromanipulation has been prevalent in recent years. Due to high biocompatibility, non-contact operation, and relatively low cost, the micromanipulation actuated by the vibration-induced acoustic ...

Arbitrary amplitude dust-acoustic waves in Jupiter atmosphere

open access: yesResults in Physics, 2021
Arbitrary amplitude dust-acoustic solitary waves in a dusty plasma in Jupiter atmosphere are expected to occur for distance greater than 15RJ, where RJis the distance from the center of the Jupiter (RJ= 71398 km).

Acoustic resonances in microfluidic chips: full-image micro-PIV experiments and numerical simulations [PDF]

open access: yes
We show that full-image micro-PIV analysis in combination with images of transient particle motion is a powerful tool for experimental studies of acoustic radiation forces and acoustic streaming in microfluidic chambers under piezo-actuation in the MHz ...

Characterizing bulk-driven acoustic streaming in air

open access: yesThe Journal of the Acoustical Society of America, 2023
The time-independent fluid flows induced by the attenuation of acoustic energy known as acoustic streaming have been experimentally measured in air using particle image velocimetry for two high powered ultrasonic transducers. The literature declares that these bulk-driven “Eckart” streaming flows are observed as turbulent jets in the direction of the ...

Microstreaming and Its Role in Applications: A Mini-Review

open access: yesFluids, 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 ...
