Cavitation M'kati mwa High-Pressure Optically Transparent Fuel Injector Nozzles(GAWO 6)
Panthawi yonse ya jakisoni, zibowo zapakhoma zimawonekera kumbali ya orifices kutali kwambiri ndi thupi la jekeseni, pomwe ngodya yolowera imakhala yakuthwa. Mabowowo amafika mpaka potulukira potulukira, kumene amagwetsa mitambo yomwe mwina imapulumuka kunja kwa jekeseniyo. Palibe umboni wa chingwe cavitation mu sac voliyumu ingawoneke, ngakhale kuti vorticity ikuwonekera m'mavidiyo othamanga kwambiri.
Ngakhale popanda chingwe cavitation, zosakhalitsa cavitation mtambo kukhetsa limapezeka pa mbali ya orifice moyang'anizana ndi kuyimirira khoma patsekeke mu orifice ndi yokulirapo kukokera ngodya kuchokera chapakati olamulira a jekeseni. Khoma loyimilira pamphuno ili limakhala m'mphepete mwa nyanja yonse, kotero mwina mitambo iyi imachotsedwa pakhoma la khoma, momwemo ingakhale chifukwa cha geometric cavitation.
Kusiyana kwakukulu pakati pa jekeseni iyi ndi majekeseni ena m'maphunziro apitalo ndi kusowa kwa singano. Choyimitsa choyimitsa chili chopanda kanthu, kotero kuti vortex yayikulu kwambiri mu sac vortex imakhala patali kwambiri pamlingo wa sac, pomwe madziwo amabwerera kumtunda kuti alowe m'miyendo ya mphuno. String cavitation pakati pa orifices sichinawonedwe mu maphunziro awa.
Mphunoyo ikalephera, kuthamanga kwa thumba la sac kumatsika mwadzidzidzi, ndipo izi zidawoneka muyeso ya sac volume pressure. Kupanikizika kwakukulu komwe mapangidwe omaliza adatha kupirira anali 600 bar. Ngakhale kuthamanga kwa jakisoniku sikuli kokwera ngati maphunziro ena am'mbuyomu, zotuluka pamphuno zamapangidwe awa ndizokulirapo modabwitsa.
4 Mapeto
Mphuno ya jekeseni yamafuta yowoneka bwino idapangidwa pogwiritsa ntchito njira yomwe imayang'ana mosamalitsa kuti phokosolo likulephera chifukwa cha zida zomwe zimagwiritsidwa ntchito pomanga.
