Manipulation mechanisms of bubble aggregation and evolution in inertial cavitation fields [PDF]
Ultrasonics SonochemistrySpherical bubble clusters was observed at 28 kHz and 40 kHz, and the evolution of the clusters was investigated. It was found that the cluster was dense when it located at the antinode of standing waves, while it became sparse when it deviates from the ...

Study of Residual Stress Using Phased Array Ultrasonics in Ti-6AL-4V Wire-Arc Additively Manufactured Components [PDF]
SensorsThis paper presents a study on residual stress measurement in wire-arc additively manufactured (WAAM) titanium samples using the non-destructive method of phased array ultrasonics. The contour method (CM) was used for the verification of the phased array

Interactions of bubbles in acoustic Lichtenberg figure
Ultrasonics Sonochemistry, 2022 The evolution of acoustic Lichtenberg figure (ALF) in ultrasound fields is studied using high-speed photography. It is observed that bubbles travel along the branch to the aggregation region of an ALF, promoting the possibility of large bubble or small ...

Radial oscillation and translational motion of a gas bubble in a micro-cavity
Ultrasonics Sonochemistry, 2022 According to classical nucleation theory, a gas nucleus can grow into a cavitation bubble when the ambient pressure is negative. Here, the growth process of a gas nucleus in a micro-cavity was simplified to two “events”, and the full confinement effect ...
