Cavitation bubble collapse close to a submerged sphere on a microscale is investigated numerically using a finite volume method in order to determine the likelihood of previously suspected mechanical effects to cause bacterial cell damage, such as impact of a high speed water jet, propagation of bub ...

Hydrodynamic cavitation poses as a promising new method for wastewater treatment as it has been shown to be able to eradicate bacteria, inactivate viruses, and destroy other biological structures, such as liposomes. Although engineers are already commercializing devices that employ cavitation, we ar ...

Numerous studies have already shown that the process of cavitation can be successfully used for water treatment and eradication of bacteria. However, most of the relevant studies are being conducted on a macro scale, so the understanding of the processes at a fundamental level remains poor. In attem ...

Nevarnosti, ki jih povzročajo drobirski tokovi in snežni plazovi ni mogoče popolnoma preprečiti. Zato
se razvijajo matematični modeli teh pojavov, kar nam omogoča, da lahko ustrezno načrtujemo
zaščitne ukrepe na ogroženih območjih. Enodimenzijski model PLAZEM15 omogoča analizo
nestalnega toka raz ...

Uporabniki cest za varno in udobno vožnjo potrebujejo ustrezna navodila. Kljub sodobnim navigacijskim sistemom GPS, se večina voznikov med potjo ravna po znakih za vodenje prometa – kažipotih. Kažipoti ljudi lahko tudi zavedejo in jih pripeljejo na napačen cilj. Diplomska naloga se loteva analize pr ...

The initial motivation for the study was to gain deeper understanding into the background of emulsion preparation by ultrasound (cavitation). In our previous work (Perdih et al., 2019) we observed rich phenomena occurring near the liquid-liquid interface which was exposed to ultrasonic cavitation. A ...

cavitation erosion;single bubble;shear flow;high speed observation;
One of the remaining open questions in cavitation erosion research is the one on the importance of the microjet and the shock wave on the formation of the pit. Up until now, no successful attempt has been made to study this in detail, mainly because the damage could only be detected and evaluated af ...

Oznake:
microbubbles;numerical analysis;cavitation;
The collapse of microbubbles near a fiber is an example often encountered in water treatment situations and cavitation fibrillation processes. However, due to the broken symmetry conditions, this process has not been studied in detail experimentally or numerically, making it difficult to precisely m ...
