Dynamic cavitation mkati mwa jekeseni wa dizilo wapamwamba kwambiri - kafukufuku woyesera ndi CFD(gawo 2)
Mu kayeseleledwe ka CFD, kuthetsa zomangira zazikulu za chipwirikiti pogwiritsa ntchito zitsanzo za Large Eddy Simulation (LES) zikuwonetsa kupindula kwakanthawi kachitidwe ka RNS [3] [4] [5]. Kuipa kwakukulu kwa LES yochokera ku CFD m'mafakitale ndizomwe zimafunikira pakompyuta, mwa dongosolo la ma cores mazana angapo odzipereka. Popanda chithandizo choterocho, nthawi yoyendetsa mlandu umodzi ingatenge miyezi yambiri, zomwe zimapangitsa kufufuza kwakukulu kukhala kosatheka mu nthawi yomveka bwino.
Zosintha zazikulu zachitika mkati mwa CFD modelling yomwe imayesa kuphatikiza mapindu a LES ndi RNS chipwirikiti modelling [6]. Mitundu iyi nthawi zambiri imatchedwa mitundu yosakanizidwa ndipo imapereka mwayi wochulukirapo kuti LES igwiritsidwe ntchito m'mafakitale.
A wosakanizidwa LES-RANS CFD chitsanzo, ntchito osakaniza Mipikisano gawo njira cavitation analengedwa kuti yesezera ntchito ya orifice ulamuliro. Mawonekedwe a chipwirikiti pogwiritsa ntchito njira yosakanizidwa ya LES-RANS amalola kupindula kwakukulu pa LES yathunthu, makamaka mu kuchuluka kwa Reynolds manambala (Re) oyenda pakhoma ma geometries mkati mwa jekeseni wa dizilo.
2. Ntchito Yoyesera
Zitsanzo zowonekera zidapangidwa ndi magawo owongolera ma hydraulic kuchokera mkati mwa jekeseni wa dizilo, kuphatikiza orifice yowongolera kuthamanga kwambiri, pakati pa singano pamwamba ndi valavu yowongolera. Chifukwa chazing'ono za majekeseni enieni chitsanzocho chinapangidwa nthawi za 40 kukula kwake kwenikweni, monga momwe zasonyezedwera m'maphunziro apitalo kuti orifice flow performance ndi yodziimira payekha payekha [1]. Kukula kumeneku kunapangitsa kuti kukhale kosavuta kuwonera pogwiritsa ntchito kamera yothamanga kwambiri, Vision Research Phantom V1210. Kamera yotereyi yokhala ndi kuyatsa koyenera imajambula tsatanetsatane wa kayendedwe kake kosawoneka ndi maso a munthu, ndipo imalola kuti machitidwe a hydraulic azitsatiridwa kudzera pa cavitation process.
