I-Cavitation Ngaphakathi koxinzelelo oluphezulu lweMibhobho yesitofu seFuel eNgaphandle(ICANDELO 5)

Uhlalutyo, uxinzelelo lwe-injection yesixhobo sangempela (i-800 bar) sisetyenziswe njengemeko yomda kwiindawo zangaphakathi zesiqwenga se-acrylic.Ngenxa yokuba izixhobo ezibuthathaka zihlala zisilela kuxinzelelo, iintambo zesafire zongezwa kuyilo lokucinezela umlomo ophuma ngaphandle kunye nokunciphisa amandla okuxinana kumphezulu ongaphakathi.Ekubeni izibophelelo zazingaphandle kombhobho, kufuneka kusetyenziswe imathiriyeli ebonakalayo ebonakalayo ekwakhiweni kwazo.

ISapphire yakhethwa ngenxa yokuqina kwayo okuphezulu.Ngandlela ithile, oku kwenza ukuba isafire ibambe izinto ezithwele umthwalo wombhobho, nangona isiqwenga apho uxinzelelo lufakwe khona ngokuthe ngqo lwenziwe nge-acrylic.

Idizayini yokugqibela ene-3 i-sapphire clamps, eyenziwe kwaye ihlanganiswe, iboniswe kwi-Figure 1. Imilinganiselo yangaphandle ye-nozzle i-21.5 mm kwindlela yokujonga kwi-Figure 1 kunye ne-6.75mm kwicala elithe nkqo.Iitywina ze-O-ring zisetyenziswa kumacala omabini omlomo.

3 Iziphumo kunye neNgxoxo

Olu luyilo lwavavanywa ngamafutha e-diesel anikezelwa yimpompo yepiston yokuthengisa ebuyisela kunye nezigaba ezi-3, eziqhutywa yimoto enkulu yombane.Ubude be-injection ye-original bubekwe kwi-250ms, kodwa imilinganiselo yoxinzelelo lwe-sac ye-sac ibonise ukuba ipompo ayikwazanga ukugcina uxinzelelo oluyalelwe kulo lonke ixesha.Isiphumo sexesha lokutofa kwaba malunga ne-100ms, kwaye uxinzelelo lwenaliti lwehla kancinci ngeli xesha.

Ukuhamba ngaphakathi kwi-nozzle kufakwe kwi-transillumination configuration kunye nekhamera ye-Phantom V1210 ephezulu.Ngenxa yokuba i-ambient yayikuxinzelelo lwangasemva lwe-atmospheric, i-orifice flow cavitated ngokulula.Umfanekiso omeleyo onoxinzelelo lwenaliti ye-350 bar iboniswe kuMzobo 2. Ividiyo epheleleyo yokuhamba kwangaphakathi kunye nokuhamba kwe-orifice kunye nommandla wokwenza isitshizi kule meko yokuhamba nayo inikezelwe.Le meko yokuhamba ikwinani le-Reynolds elimalunga nama-85,000.
