I-Cavitation Ngaphakathi koxinzelelo oluphezulu lweMibhobho yesitofu seFuel eNgaphandle(ICANDELO 7)

4 Izigqibo (ziyaqhuba)

Le ndlela ithathela ingqalelo ezona ndlela zixhaphakileyo zokungaphumeleli kwezixhobo ezibhityileyo, kwaye yasebenzisa iFinite Element Analysis ukusombulula imithwalo yokusebenza kumbhobho ngokweenkcukacha. Uyilo lusebenzise izibane zesafire ezinejometri ezilula ukucinezela isiqwenga sombhobho we-acrylic ukuze kuncitshiswe ukuxinzelela koxinzelelo kwimigangatho engaphakathi yesiqwenga apho kufakwe khona uxinzelelo olusuka kumafutha. Ngomthamo onikiweyo woxinzelelo, olu luyilo luxabisa ngaphantsi kunolwakhiwe kuphela ngesafire kwaye lomelele ngakumbi kunolwakhiwe nge-acrylic kuphela.

I-cavitation kwii-orifices ibonise ukuxhomekeka kwijometri, ngokukodwa kwi-angle inclination angle of the central axis of the orifice. Nangona i-cavitation ifunyenwe kumacala omabini e-orifice kunye ne-angle inclination angle enkulu, kwakungekho ngenxa ye-string cavitation, yintoni i-cavitation kule ndawo ixhaphake kakhulu kwizifundo ezidlulileyo.

Umsebenzi wexesha elizayo uya kususa imingxuma yokucocwa kwiintambo zesafire, kwaye endaweni yoko sebenzisa iziqwenga zesafire ezilula ezifakwe ngaphakathi kweentsimbi zentsimbi. Olu tshintsho lulindeleke ukuba lunciphise uxinzelelo loxinzelelo kwiziqwenga zesafire kwaye luvumele amandla amakhulu okubamba kunokuba bekunokwenzeka ngoyilo lwangaphambili.

Iziqwenga ezitsha ziya kuvavanywa ukuqinisekisa ukusebenza kwazo kwaye ke iimvavanyo ziya kuqhutywa phezu koluhlu lweengcinezelo zangasemva (i-cavitation umbers) kwigumbi elicinezelekileyo. Oku kuya kuvelisa uluhlu lokuhamba kwe-cavitating ukwenzela ukuqhubela phambili ukufunda.

5 Imibulelo

Ababhali bangathanda ukubulela i-EU ngokuxhasa lo msebenzi phantsi kweprojekthi ye-HERCULES-C, kunye nokubulela i-Swedish Energy Agency ngenkxaso yabo.
