Study of hydrodynamic cavitation in static appliances for industrial application

, 2023
reservedCavitation identifies the appearance of vapor cavities inside an initially homogeneous liquid medium. Bubbles formation and growth are due to a sharp decrease of local pressure below the saturation pressure of the state.

Inactivation of the enveloped virus phi6 with hydrodynamic cavitation

Ultrasonics Sonochemistry, 2023
The COVID -19 pandemic reminded us that we need better contingency plans to prevent the spread of infectious agents and the occurrence of epidemics or pandemics. Although the transmissibility of SARS-CoV-2 in water has not been confirmed, there are studies that have reported on the presence of infectious coronaviruses in water and wastewater samples ...

Imaging the cellular response to transient shear stress using time-resolved digital holography

, 2014
Shear stress has been recognized as one of the biophysical methods by which to permeabilize plasma membranes of cells. In particular, high pressure transient hydrodynamic flows created by laser-induced cavitation have been shown to lead to the uptake of ...

Luminescence from hydrodynamic cavitation [PDF]

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
The majority of the research on cavitation luminescence has focused on the sonoluminescence or chemiluminescence generated by cavitation induced through ultrasound, with a lesser body of work on the luminescence induced by laser- or spark-induced cavitation.
