Numerical modelling and experimental validation of an orifice plate-based hydrodynamic cavitation process for improving the biomass pretreatment [PDF]

open access: yesBiotechnology Reports
Hydrodynamic cavitation can be used to pretreat biomass by utilizing the energy released during the collapse of cavitation bubbles. Delignification as pretreatment enhances the biodegradation of lignocellulosic composition.

Coronary artery cavitation as a trigger for atherosclerotic plaque progression: a simplified numerical and computational fluid dynamic demonstration [PDF]

open access: yesReviews in Cardiovascular Medicine, 2022
Backgrounds: Coronary cavitation is supposed to be generated by both concentric and eccentric coronary artery stenosis which propagates downstream the vessel, creating microbubbles which exploded when the fluid pressure was lower than the vapor ...
