KUTEVEDZERA KWAKUKURA KWEKUTEVERA MUFUEL INJECTOR NOZZLES (chikamu 1)

Atomization yemafuta yakakosha mukudzora kupisa mukati mejini yakananga jekiseni. Kudzora kupisa kunobatsira mukuderedza kuburitsa uye kuwedzera kushanda zvakanaka. Cavitation ndechimwe chezvinhu zvinonyanya kukanganisa hunhu hwekupfapfaidza mukamuri rinopisa. Majekiseni emafuta emhando madiki uye anoshanda nekumanikidza kwakanyanya, izvo zvinodzikamisa kudzidza kwemukati menozzle maitiro. Zvikero zvenguva nehurefu zvinowedzera kudzikamisa chidzidzo chekuyedza chejojo ​​jekiseni remafuta. Simulating cavitation mune injector yemafuta ichabatsira mukunzwisisa chiitiko uye ichabatsira mukuwedzera kusimudzira.

Kuvakwa kwechero kuenzanisa kwecavitating injector nozzles kunotanga nefungidziro dzakakosha dzekuti zviitiko zvichasanganisirwa uye izvo zvicharegeredzwa. Kusvika iye zvino, hapana kubvumirana pamusoro pekuti zvinogamuchirwa here kufunga kuti zviduku, high-speed cavitating nozzles zviri mu thermal kana inertial equilibrium.

Izvi zvakasiyana-siyana zvemafungiro zvinotungamirira kune zvakasiyana-siyana zvekuenzanisira maitiro. Kana munhu akafunga kuti muromo uri mukupisa kuenzana, saka hapana kunonoka kunonoka Vi mukukura kwebubble kana kudonha nekuda kwekutamisa kupisa. Kutamisa kupisa kunokurumidza kukurumidza uye inertial mhedzisiro inomisa shanduko yechikamu.

Kufungidzira kweinertial equilibrium kunoreva kuti zvikamu zviviri izvi zvine slip velocity isingaite. Neimwe nzira, pane sub-grid scale level, munhu anogona zvakare kufunga nezve mukana wemabhuru madiki ane saizi inopindura shanduko mukumanikidza. Schmidt et al. [1,2] yakagadzira maviri dimensional inopfupika homogeneous equilibrium modhi yaive yakagadzirirwa kutevedzera diki, inomhanya muromo inoyerera. Iyo HEM inoshandisa fungidziro yekudziya kwekuenzanisa kutevedzera cavitation. Iyo inotora maviri-chikamu kuyerera mukati memuromo muhomogeneous musanganiswa wemhute uye mvura.

Iri basa rinopa kuenzanisira kwepamusoro-kumhanya nozzle, uchishandisa iyo HEM yecavitation, mune yakawanda-yakawanda uye yakafanana chimiro. Iyo modhi inowedzerwa kuti itevedzere iyo isiri-mutsara mhedzisiro yechikamu chakachena mukuyerera uye nzira yenhamba inogadziriswa kuti iwane yakagadzikana mhedzisiro mumultidimensional framework.
