20.500.12556/RUL-125677 Numerical insight into the Kelvin-Helmholtz instability appearance in cavitating flow Recently the development of Kelvin-Helmholtz instability in cavitating flow in Venturi microchannels was discovered. Its importance is not negligible, as it destabilizes the shear layer and promotes instabilities and turbulent eddies formation in the vapor region, having low density and momentum. In the present paper, we give a very brief summary of the experimental findings and in the following, we use a computational fluid dynamics (CFD) study to peek deeper into the onset of the Kelvin-Helmholtz instability and its effect on the dynamics of the cavitation cloud shedding. Finally, it is shown that Kelvin-Helmholtz instability is beside the re-entrant jet and the condensation shock wave the third mechanism of cavitation cloud shedding in Venturi microchannels. The shedding process is quasi-periodic. cavitation Kelvin-Helmholtz instability microchannel numerical simulation kavitacija Kelvin-Helmholtzova nestabilnost mikrokanali numerične simulacije true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-01 14:28:49 2021-04-01 14:28:51 2022-09-05 03:52:01 0000-00-00 00:00:00 2021 0 0 12 str. iss. 6, art. 2644 Vol. 11 Mar. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.876.5:532.528(045) 2076-3417 10.3390/app11062644 56979971 RAZ_Pipp_Peter_2021.pdf RAZ_Pipp_Peter_2021.pdf 1 43927D2E1FF18E814A8DD5F27FC4053C 5b63936894835c7224528fd64d8c2ab053b830152b084cf722694c1d70d8469a cca25451-9aef-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154227 https://www.mdpi.com/2076-3417/11/6/2644 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141506 Fakulteta za strojništvo 0 0 0
