The inertial cavitation of bubble clouds has been considered to be the hidden crucial mechanism for recent new therapeutic ultrasound applications such as Histotripsy and the ultrasound drug delivery. Although many models are already put forward to simulate the cavitation process, due to the inaccessible experimental validation, which model works closest to the real world situation is not well ...

Cavitation instabilities can induce axial and circumferential vibrations, as well noise in turbopump inducers. Therefore, the purpose of present study is to investigate mechanism cavitation instability. The flow field near two-bladed inducer leading edge under alternate blade was experimentally investigated using particle image velocimetry (PIV). It found that tip leakage vortex draws toward it...

The research on cavitation bubbles within droplets has gradually become one of the advanced topics in field confined fluid domains, which is closely related to industry fields. However, relationship between collapsing droplet and splash dynamics still its infancy. Here, high-speed photography experimental platform was built investigate influences eccentricities phenomenon. concluding remarks ar...

Abstract The asymmetric collapse of cavitation bubbles near a solid substrate generates large wall shear stresses, the precise magnitude which is still not known with certainty. By comparing numerical simulations and experiments laser‐induced bubble substrate, we demonstrate that an accurate measurement pressure pulse emitted during inception maximum radius allow unique initialisation simulatio...
