Bubble cloud-mediated cavitation for tumor mechanical ablation and effector immune cell deployment [PDF]

Ultrasonics Sonochemistry
Histotripsy is a cavitation-based tumor ablation technology. To achieve precise cavitation-based ablation requires investigating the cavitation behavior of the bubble cloud and their impact on tumor tissue.

Experimental and Numerical Studies of Cloud Cavitation Behavior around a Reversible S-Shaped Hydrofoil

Journal of Marine Science and Engineering, 2022
The S-shaped hydrofoil is often used in the design of reversible machinery due to its centrally symmetrical camber line. The objective of this paper is to study the influence of cloud cavitation on the flow structure and the unsteady characteristics of ...

Revealing the interplay between flow dynamics and cavitation activity in a flow-through sonoreactor [PDF]

Ultrasonics Sonochemistry
Acoustic cavitation is a well-known approach to intensify chemical and physical processes. Despite extensive studies in the understanding of batch ultrasonic reactors, flow-through sonoreactors, which are more relevant to continuous and large-scale ...

Research on Cavitation Characteristics of Two-Throat Nozzle Submerged Jet

Applied Sciences, 2022
Ship fouling not only increases ship resistance and fuel consumption but is equally a type of biological invasion, which causes severe ecological damage. Submerged cavitation jet cleaning is an environmentally friendly, high-efficiency, and energy-saving

Numerical Study on the Vibration and Noise Characteristics of a Delft Twist11 Hydrofoil

Journal of Marine Science and Engineering, 2021
Underwater radiated noise (URN) is greatly increasing due to an increase in commercial shipping, sonar activities, and climate change. As a result, marine life is having difficulty communicating, and marine ecosystem disturbances are occurring. The noise

Experimental study on the boundary layer of the NACA16-012 hydrofoil during the cavitation disappearance phenomenon

Journal of Fluid Science and Technology, 2022
The generated cavitation on the NACA16-012 hydrofoil suddenly disappears at a specific angle of attack, even at a low cavitation number, where cavitation normally develops. This was named the cavitation disappearance phenomenon by the authors. It has not
