Hydrodynamic Cavitation‐Induced Thrombolysis on a Clot‐on‐a‐Chip Platform

Advanced NanoBiomed Research, Volume 5, Issue 1, January 2025.
A new clot‐on‐a‐chip platform leverages microfluidic devices to control hydrodynamic cavitation (HC) for targeted blood clot erosion. Reduction on clot mass and diameter and scanning electron microscopy analysis confirm progressive clot erosion with increasing HC intensity.

Cavitation Observations in a Jet-Flow Gate-Valve

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1984
As a step for clarification of the mechanism of cavitation erosion as well as noises at a jet-flow gate-valve, the cavitation-aspects and the associated sound-pressures were simultaneously observed systematically by means of high-speed-photography and sensitive pressure-detection through a hydrophone, in a 1/10-scale model-valve for various openings ...

Instantaneous Behavior of Cavitation Clouds at Impingement of Cavitating Water-Jet

Progress in Multiphase Flow Research, 2007
It is known that water-jet with cavitation clouds shows unsteady behavior and causes high impact. It is useful for not only the water jet technology but also various engineering fields. The unsteadiness of cavitation clouds is one of the most interesting problems for the use of the cavitating water-jet.
