Babban Eddy Simulation na injector dizal yana buɗewa tare da ƙirar cavitation na lokaci biyu(part 1)
Abstract.
A cikin takarda na yanzu, an gabatar da sakamako masu nuni na kwaikwaiyo masu gudana yayin lokacin buɗewar injector Diesel. Domin kama hadadden filin kwarara da tsarin cavitation da ke samuwa a cikin injector, An yi amfani da Large Eddy Simulation, yayin da aka haɗa da matsa lamba na ruwa. Don yin la'akari da tasirin cavitation, an yi amfani da samfurin gauraya mai kama da kashi biyu.
An daidaita yawan canja wurin taro na samfurin cakuda don iyakance gwargwadon yiwuwar faruwar matsi mara kyau. A lokacin simintin, an sami kololuwar matsa lamba a wuraren da tururi ya ruguje, tare da girman da ya wuce 4000bar, wanda ya fi girma da yawan damuwa na kayan gama gari. Wuraren irin waɗannan kololuwar matsa lamba sun yi daidai da ainihin wurin da zaizayar ƙasa kamar yadda aka samo daga sikanin X ray.
1. Gabatarwa
Tsarin alluran Diesel yana taka muhimmiyar rawa a cikin injunan konewa na ciki tunda suna shafar samuwar feshin mai, atomization da konewa, fitar da hayaki da ingancin injin. Gudun jet ɗin da aka kafa suna cikin tsari na 500m/s, tare da matsatsi na sama a kusa da 2000bar. Abubuwan da ke faruwa a yanzu suna nuna matsin lamba na allura har zuwa 3000bar, don saduwa da dokokin EU na gaba a cikin hayaki. Koyaya, matakan matsa lamba mafi girma suna haifar da saurin gaske ta hanyar tsauraran wurare a cikin injector dizal da haɓaka mai ƙarfi a cikin canje-canje masu kaifi (kusurwoyi, fillet da sauransu), wanda ke haifar da matsa lamba na gida yana faduwa ƙasa da matsi na jikewa da haifar da cavitation.
Bugu da ƙari kuma, cavitation na iya haifar da lalacewar cavitation yashwar jiki da kuma mummunar lalacewar aikin injector, har ma da mummunar lalacewar injector, wanda zai iya lalata injin, idan tip ɗin injector ya ƙare. An yi ƙoƙarce-ƙoƙarce da yawa don hasashen zaizayar injector Diesel, duba misali aikin Koukouvinis et al. [1].
