I-Dynamic cavitation ngaphakathi komjovo wedizili osebenza kakhulu - uphenyo lokuhlola kanye ne-CFD (ingxenye 1)

Abstract.

Inhlanganisela yokulingisa kanye namasu okuhlola akhethekile asetshenziselwe ukuphenya ukugeleza kwesikhashana kanye nezenzakalo ze-cavitation zedivayisi yokulawula ngaphakathi komjovo wedizili osebenza kakhulu.Ukuziphatha kwe-Dynamic cavitation kwathwetshulwa ngemodeli enkulu esobala, eyabe isisetshenziswa ukuthuthukisa nokuqinisekisa imodeli ye-CFD yesiphithiphithi esithuthukisiwe nge-Large Eddy Simulation.Lawa masu asetshenziswa ngaphakathi kwe-Delphi ukuze athole ukuqonda futhi athuthukise ukusebenza komjovo ngosayizi wangempela.

1 Isingeniso

Umjovo wedizili ngokungangabazeki uyinto ebaluleke kakhulu ekuzuzeni ukusebenza kwenjini ye-premium enekhabhoni ephansi.Ngakho-ke kulandela ukuthi ama-injection ezinjini ezisebenza kahle kufanele alawulwe ngokunemba.Ngenxa yalokhu, ama-valve okulawula amanzi angaphansi komhlaba kanye nezisekelo kufanele aklanywe futhi akhiqizwe ngokunemba okuphezulu, futhi ukuqonda ukuziphatha kwawo okuyisisekelo kuzonikeza umnikelo obalulekile enqubweni yokwenza kahle nokuhlela kahle.I-Delphi isebenzisa inhlanganisela yokulingisa kanye namasu okuhlola akhethekile ukuze iphenye izici zokugeleza zalezi zisetshenziswa.

Njengawo wonke ama-injection amasha, i-High Performance Diesel Injector ngaphansi kokuthuthukiswa e-Delphi ibe isihloko somsebenzi omningi wokulingisa.Okuthakazelisa kakhulu leli phepha, uphenyo lwe-CFD lwemisebenzi yokulawula amanzi angaphansi komhlaba.

I-Flow cavitation yisihloko esijwayelekile emishini yokujova udizili;isipiliyoni sokuhlola sangaphambilini sibonise ukuthi imodeli yemboni ye-Reynolds-Averaged Navier-Stokes (RANS) ayikwazanga ukunikeza imiphumela enembile yokuziphatha kwe-cavitation enamandla.Ngakho-ke ngaphezu komsebenzi we-CFD, amamodeli wezinga elikhulu (LSM) ezingxenyeni ezahlukene zemisebenzi yokulawula amanzi asetshenziswayo agunyazwa.Ukusetshenziswa kwamamodeli abonisa ngale wamavalvu okulawula kanye nezingosi ezikalini ezikhuphuke kakhulu kuvumela ukuqonda okuthuthukisiwe kokusebenza kwe-hydraulic [1] okungafinyeleleki kalula ngamanye amasu.Ukusebenza kwe-hydraulic kuzimele ngokwanele kuzo zonke izikali ukuze kube usizo njengethuluzi lokuthuthukisa [2].
