A Study of Instability Mechanisms Driving Cloud Cavitation: Experimental Analysis Using New Advanced Velocimetry and Evaluation of Numerical Models
Hydrodynamic cloud cavitation, characterized by the periodic shedding and violent collapse of large vapor structures, poses significant risks to the integrity and performance of hydraulic machinery. Despite extensive research, the precise interaction between competing shedding mechanisms, …

Data Analysis of an Unsteady Cavitating Flow on a Venturi-type Profile
… are corresponding to slow-varying drift flow, cloud-shedding, and Kelvin-Helmholtz (KH) instability for a fixed inlet flow condition. The high coherence measure obtained from the instabilities suggests a transfer of energy from the largest scales, fluctuating mean flow, to the smaller scales …

Ultrasonic Effervescence: Investigations of the Nucleation and Dynamics of Acoustic Cavitation for Histotripsy-Based Therapies
… homogenate through the generation of acoustic cavitation and is currently being developed for numerous clinical applications. Histotripsy uses high-pressure (>10 MPa), short-duration (<15 cycles) pulses to cause the rapid expansion and collapse of nuclei at the focus resulting in large applied …

Experimental investigation of cavitation in a cylindrical orifice
… and agriculture. While, the presence of cavitation in plain orifice atomisers is known to enhance this process, the complex flow mechanisms that result within the nozzle, such as periodic cavitation shedding, are not fully understood. A new cavitation research rig was designed and built …
