Tasirin diamita bututun ƙarfe, matsa lamba na allura da zafin yanayi akan halayen feshi a injin dizal(Kashi na 3)

3. Sakamako da tattaunawa

Wannan bincike ya yi amfani da diamita daban-daban guda biyu wanda shine 0.20 mm da 0.12 mm. Wannan simintin ta amfani da yanayin yanayin yanayi daban-daban akan 500 K da 700 K don kowane matsa lamba na allura yana kwaikwayon 40 MPa, 70 MPa da 140 MPa. Manufar wannan simintin ita ce bincika nau'ikan nau'ikan feshi daban-daban waɗanda ke tasiri da diamita na bututun ƙarfe, zafin yanayi da matsa lamba na injin dizal. Binciken halayen fesa na wannan simintin ya fi mayar da hankali ga diamita na droplet, tsayin shiga da tsayin fashewa wanda ke tasiri daga siga. An gwada hankalin grid akan ƙirar tare da girman grid daban-daban. Girman grid ya kasu kashi uku matakai waɗanda ke da ƙaƙƙarfan grid, matsakaici da lafiya. Tebur na 2 yana nuna adadin abubuwa da nodes ga kowane rukuni na girman grid daban-daban.

Bayan haka, adadin abubuwa yana jere daga 24997 zuwa 114555 abubuwa. Adadin abubuwan a fili yana daidai da lambobin nodes ta hanyar hawan matakin girman grid daga m zuwa lafiya tare da matakin santsi daga ƙasa zuwa babba.

Diamita diamita na feshin yana kasancewa Hoto na 6 yana nuna cewa a diamita na diamita na 40 MPa a 0.20 mm da 500 K siga yana nuna ƙarin girman launin ja yana wakiltar babban ɗigon digo idan aka kwatanta da 0.12 mm 700 K. Girman rarraba digo na 0.12 mm kuma 0.2 mm ana nuna su a cikin hoto na 7 da 8. Kamar yadda aka kwatanta a cikin jadawali, sun nuna cewa tsarin girman rarrabawar droplet daidai yake da juna. Mafi girman zafin yanayi da matsa lamba na allura suna ba da ƙaramin diamita.

Sakamakon ya bayyana cewa ɗan ƙaramin man da aka yi a cikin ɗakin zai iya haifar da ƙananan konewa. A lokaci guda diamita droplet dogara a kan aerodynamic ja a cikin dakin zai iya rinjayar droplet diamita yi karami lokacin da iska karo da man fetur.
