Cavitation Mukati Yepamusoro-Kudzvanya Optically Transparent Fuel Injector Nozzles(CHIKAMU 1)

Nhanganyaya Yakakwirisa majekiseni anomanikidza uye microscopic nozzle orifices anoshandiswa mumajekiseni masisitimu mumajini emazuva ano akananga majekiseni kusimudzira atomization uye kuendesa huwandu hwehuturu hwakakwana nekukurumidza. Kuyerera kuri mukati mejekiseni kunofanira kungoerekana kwaita kuti ipinde mugomba remuromo, izvo muzviitiko zvakawanda zvinoita kuti cavitation ioneke kudivi rezasi rekona yekupinda mukati. Cavitation inowanzoonekwa sengozi, nekuti kudonha kwecavitation mabhubhu kunogona kukuvadza nzvimbo dzesimbi dzakasimba sesimbi dzakaomeswa. Mukuwedzera, nepo mamwe maitiro e cavitation akaratidzwa kuti anobatsira atomization, kunyange kubvisa carbon deposits mu petrol injectors, hydraulic flip inodzvinyirira atomization zvachose[1]. Kusvikira cavitation inonzwisiswa zviri nani uye nyore kudzora, zvinoratidzika zvine musoro kugadzira iyo injector nozzle nenzira yekudzivirira cavitation. Iyo inonyanya kushanda nzira yekufunda nozzle orifice flow cavitation ndeyekuvaka jekiseni rine optical inosvikika nozzle kuitira kuti orifice inoyerera ionekwe zvakananga. Iri harisi basa riri nyore. Optical transparent engineering zvinhu zvinowanzo brittle pakupisa kwekamuri. Nepo brittle zvinhu zvinowanzove nepamusoro elastic moduli uye akasimba etioretical simba, zvikanganiso zvakasiiwa kubva pakugadziriswa kunodiwa kugadzira iyo inodiwa geometry inogona kuderedza zvakanyanya kuremerwa kwechikamu chakapedzwa. Nyaya yakakosha ine optical matipi ndeyekutsvaga mucheno pakati pemaindices erefraction yenozzle zvinhu uye fluid inoshandiswa. Kana iwo asina kufananidzwa, ipapo mipendero yevhesi ichaonekwa yakasviba mune shadowgram. Izvozvo zvingaita kuti zvive zvakaoma kufananidzira rusvingo cavitation.

Acrylic uye quartz vane index inouya pedyo neiyo yemafuta akawanda (uye mvura) asi zvinosuruvarisa kuti vane simba rakaderera nekuda kwekugadzirisa kukanganisa. Anowanzo kutyora zviri pasi pezvinoita mafuta anomanikidza. Sapphire, kune rumwe rutivi, ine kupisa uye simba zvimiro zvakafanana nesimbi, asi haina kunaka index inofananidzwa nemvura yekufarira.
